Nice article for engineers to understand something that most guitar players will intuitively know.
One of the great things about a hi-gain setup like Hendrix's is how the feedback loop will inject an element of controlled chaos into the sound. It allows for emergent fluctuations in timbre that Hendrix can wrangle, but never fully control. It's the squealing, chaotic element in something like his 'Star Spangled Banner'. It's a positive feedback loop that can run away from the player and create all kinds of unexpected elements.
The art of Hendrix's playing, then, is partly in how he harnessed that sound and integrated it into his voice. And of course, he's a force of nature when he does so.
A great place to hear artful feedback would be the intro to Prince's 'Computer Blue'. It's the squealing "birdsong" at the beginning and ending of the record. You can hear it particularly well if you search for 'Computer Blue - Hallway Speech Version' with the extended intro.
> The way you can hear the machine guns, choppers, sirens, screaming in agony…
You know, I've heard that performance so many times over so many decades that I don't have to hit a play button or even close my eyes in order to hear it. It's there inside my head when I want it to be.
And somehow I never interpreted it in that way (sirens, screaming, etc) until just a moment ago. I thought it was just a quirky little early-morning break in the familiar tune from someone who had been up way too long by that point.
And now instead of just being the quirky sounds of an impromptu guitar solo that I can recall whenever I wish, it now has unpleasant pictures to go with it.
The imagery of 1969, I remember it well. The Vietnam war was the first war that was televised. Everyone would watch the nightly news at 6:30 pm (take my word for it) and hear the choppers, gunfire and real life screams of people.
I thought it was sheer genius that Hendrix was able to subtly bring that into the national anthem which made it resonate so well with those purchasing his music. But without that background reference I never supposed that younger generations would hear it entirely differently.
I've not listened to that song much at all. I am however obsessed with Machine Gun which has all those elements and more. Maybe I'll have a re-listen to SSB.
I wonder if tube harmonics modeled by solid state settings has shaped music. Of course it has; music from that era is instrument-oriented.
The discovery of feedback tones and the resulting incorporation in the musical experience — a three hour warm bank of tubes turned up to the limit with a maxxed out savant unlocking new realms of sound.
I think I recall reading about Hendrix that he tried to emulate the sounds of cartoons with his guitar, and then when he was in the army he did the same with trying to reproduce the sounds of fighter jets. Not sure if urban legend, but cool origin story.
> I don't think Hendrix was on a 'mission' to solve engineering puzzles at all. He was just experimenting, as an artist.
1,000,000%. Guitar is one of those hobbies where people mythologize and build elaborate hagiographies around players they like and the gear that they used. Hendrix was a generational talent but I highly doubt he was sitting around enumerating problem statements and systematically exploring solution spaces. The Fuzz Face was one of like four dirtboxes available during that time so he chose that one. He flipped a guitar upside down because he could source one more easily than a lefty model. He leveraged feedback because he discovered it naturally and realized that he could make it sound totally badass.
The man clearly had a vision and executed it but his decisions were pragmatic, not the product of grand technical reasoning. It reminds me of the student who wrote a bunch of authors and asked to what degree they were conscious of the themes and symbolism in their work [1]. Many were not - as it turns out English teachers often put the cart before the horse. This is the rock and roll version of that.
I can't knock the article though as it has a lot of sound (pun intended) analysis in it as opposed to typical guitar forum dreck about NOS tube and hand-wired turret board magic.
> He flipped a guitar upside down because he could source one more easily than a lefty model.
I've read that he claimed he played a right-handed guitar upside down because his father was superstitious and didn't like him doing things left-handed, so he'd play a right-handed guitar upside down most of the time and flip it over when he needed to play in front of his father. (I'm not sure why he didn't play a lefty guitar upside if that was the case, but I could imagine that the availability might be relevant like you mentioned, or maybe his father was familiar enough with guitars to be able to recognize a left-handed one and figure out what was going on, or maybe because he was better left-handed he could play it upside-down well enough but due to not being right-handed he would have found it more difficult to play it in the non-standard way).
Interesting factoid: modern guitar effects typically have their input jacks on the right-hand side, and output jacks on the left. In this article's guitar rig diagram, the jacks are reversed, but this is accurate: back then, for whatever reason the jacks were reversed on each of these pedals. Modern reissues of the round-enclosure Fuzz Face pedals preserve this pattern despite the reversal of industry trends.
> Electric guitars attack hard, decay fast, and don’t sustain like bowed strings or organs.
Since the 1980s, we have had the "Sustainiac": an active circuit installed in the electric guitar along with a "reverse pickup" which is energized in order to excite vibration in the strings.
With this device, at the flip of a switch, you get indefinite sustain on any note on the neck, at any volume, distortion or not --- even if the electric guitar is not plugged into an amplifier at all, and just heard acoustically.
The best implementations of this have a three way harmonic switch. You can choose between excite the fretted (or open) note itself (fundamenta a.k.a first harmonic), an octave above it (second harmonic) or a higher harmonic still.
You can be sustaning the given note, and then at the flip of a switch, it will fade over to the higher harmonic.
YouTube videos of this in action are worth checking out.
If you don't want to or can't install a Sustainiac pickup, you can get a much cheaper handheld one-string "E-Bow" that does the same thing. It's not as easy to use as a Sustainiac and you can't also be playing with the whammy bar unlike with a Sustainiac, but you can get it to do tricks a Sustainiac can't do: see the "spiccato" section in https://www.youtube.com/watch?v=b0V3pzxma-8
I've also managed to make an E-Bow work with a steel-string acoustic guitar (but only on one string IIRC).
I strongly believe that if you set aside genre preferences the solid body electric guitar coupled to a tube amplifier is objectively the greatest electronic instrument ever created.
All other electronic instruments, with the one exception being the Theramin, have a fundamental problem with human expression. There is an unsolvable disconnect between what the performer's actions and their audience.
With an electric guitar you get the physicality and dynamism of an acoustic instrument with the complex timbres and extended technique possibilities of an electric/electronic instrument.
There are complex and musically significant feedback loops occurring across many dimensions that lead to extremely complex transformations of timbre via both traditional music theoretical techniques and the physics of a tube amplifier combined with an inductive load (the guitar pickup).
Its really crazy how much more dynamic and complex this can be then even a highly sophisticated modular synthesizer or whatever. Even the way you over load the power supply in a tube amplifier can be manipulated on the fly to enhance and transform timbre.
Then on top of all that it is so incredibly physical that a performer like Jimi Hendrix can manipulate these systems and have the audience intuitively understand what he is doing. Never in a million years would THAT be possible with any other electronic instrument.
The reverse example of this is musicians who play techno with analog instruments, like Pipe Guy, Basstong, and Meute[0][1][2].
There are always some people who get extremely defensive whenever I say that techno didn't click for me until I heard this kind of "techlow" music. Specifically about the part where I think that the reason is also a human expression problem, because of limitations imposed by the electronic media used.
EDIT: having said that, I don't think I would agree with your premise, because it is colored by a subtle form of survivor bias. None of us remember what it's like to not know electronic guitars or what they sound like, so claiming "the audience intuitively understands what Jimmy Hendrix is doing" is like saying everyone "intuitively understands" their native language. On top of that there's nothing about the workings of an electronic guitar that wouldn't in principle work for something like an electronic violin or whatever.
> There are always some people who get extremely defensive whenever I say that techno didn't click for me until I heard this kind of "techlow" music.

I guess the part people don't like hearing is the implication techno is somehow not expressive. I'm not sure that it lacks expressiveness, but it is certainly more "controlled" than traditional music. When I first heard techno as a teenager in the 90s, my mind was blown. I remember exactly where I was the first time I heard Underworld [1], Photek [2], and Autechre [3]. I think I was attracted to these sounds _because_ they were so different. I think it's hard for electronic music fans like myself to accept the idea that it isn't expressive _because_ it is so different. Isn't it just a different kind of expression?
Still, people like what they like. I'm glad you found a version of dance music that works for you. I've long since moved on being judgmental about people's musical tastes. I think it's just wonderful that music exists at all!
Legends Never Die - Leagueoflegends + Ethnic Instruments by Belle Sisoski [1]. And no, I've never played LoL, I probably never will, and I haven't seen that series based on it (Arcana or something?) either.
Also, I haven't checked what Juno Reactor do these days, but their old work is phantastic. My fav show of them is Juno Reactor – Shango Tour 2001 Tokyo [2].
For electric violin, I love Ed Alleyne-Johnson [3]. Never seen him live (I'm not from UK) but I own a couple of his earlier works. It reminds me of that time when my dad was in his final years of his lives, and when he finally passed away. Makes me cry every time.
You might also enjoy Beardyman, if you haven't run across him yet. Does techno and other genres with nothing but his own voice and a shedload of ipads: https://www.youtube.com/watch?v=DYVUlx7BhhI
Nathan Flutebox Lee and Beardyman @ Google, London [1] is one of my favs. At the time it was available on 'Google Video' before they acquired YouTube. So I don't have a link to the orig. post. SPOILER: especially that theme with the Godfather when he says Google is just epic and balls.
Nice addition! First time I heard of them and I'm liking what I'm hearing so far.
And just to clarify: I don't dislike electronic instruments. I just think that on some subconscious level the human brain can detect other humans playing a live instrument. Like there's something "embodied" in the sound that is likely missing from a pure electronic instrument. And I needed that element to "unlock" access to techno.
Yep, there's a reason we have the industry term "humanization" in sound design, composition and arrangement.
Tons of work has been done on various modes of humanization by trying to parameterize and modulate these aspects over time. Timing accuracy, velocity variance, chance, etc.
A well-played instrument certainly feels like someone speaking and expressing themselves to you. There are attempts to capture this with MPE instruments such as the Osmose, or Imogen Heap's MiMU gloves.
Hmmm, I disagree, having played electric and acoustic guitars for over two decades and begun learning piano and synths for the first time in 2025.
For one, you can’t easily play two melodies simultaneously across several octaves, using both of your hands, with an electric guitar.
Stringed electronic instruments do have their advantages, but so do the others. Each music making thing has its place in the spectrum.
Two books that have helped me greatly in my musical life, in case people haven’t heard of them, are The Listening Book, and Bridge of Waves, by W.A. Mathieu.
> There is an unsolvable disconnect between what the performer's actions and their audience
Is that really true though? If I watch a cellist play I can pretty clearly see all the things they are doing and it will correlate neatly to the timbre of the sound.
Secondly I think it's important to note the tube amp and the guitar are seperable, and I don't think that their connection is particularly magical. I can reamp a sound from my synthesizer (or maybe a keytar?) into a guitar chain, and if I manipulate the mic and other controls in the same way I might manipulate the pickup, I can also get all manner of interesting feedback effects. My inputs will have different harmonic characteristics of course, and the tube amp's effects are mostly transformations of harmonics; you'll still get some cool tones and they will be subject to a lot of the same rules as if a guitar was being played.
They're talking about electronic instruments there. The comment is about how electronic instruments don't generally match the physical expressiveness of acoustic instruments (like the Cello).
I'm talking about electronic instruments how they are deficient in expressiveness compared to your cello example.
> Secondly I think it's important to note the tube amp and the guitar are seperable, and I don't think that their connection is particularly magical.

The story is not quite so simple. Your synthesizer is going to have a buffered output so it wont have the complex impedance loading interactions with the amplifier as the guitar pickup.
This is actually critical to how early distortion effects such as the classic Fuzzface work and imo is essential for the kind of complex timbres you can produce with a guitar + tube amp.
In fact you can take an electric guitar, put a buffer pedal in the chain between your fuzz pedal and amp and completely destroy the ability to produce wild feedback and distortion.
I'm a guitarist, but there's nothing particularly magical about a high impedance signal, other than they tend to lead to noise and make really obnoxious things matter, like how low capacitance your cable is. Also, a TON of modern guitars are low(ish) impedance out because they use active pickups.
The pedals and system being dependent on the high impedance was always a bug, not a feature, and make the setup incredibly dependent on variables that really wouldn't be that hard to just buffer then recreate deterministically. Like, if your pedal should react to that impedance just buffer the front, put a big inductor (or a transformer using only half, or, - and I've actually seen this - just a whole guitar pickup) in the pedal. Then you're not dependent on the pickups of the guitar or the capacitance of cable or anything else and you can make sure the effect sounds good regardless of pickup type.
That is going to be something like a transformer to step down your line level signal and some series resistance to match the load to help drive the amp.
An actual coil pickup has reactive impedance that is frequency dependent and will result in a more complex interaction between the devices.
> The pedals and system being dependent on the high impedance was always a bug, not a feature
Sure if you think like an engineer, but everything you are complaining about is what allows someone like Jimi Hendrix to do what he did with a guitar.
they're comparing an electric guitar to electronic instruments, like midi keyboards. An electric cello would be the same thing as an electric guitar in this context.
Great argument -- but I'd also counter that "the turntable" (i.e. in the hands of experts like Q-Bert, Craze, Rob Swift, Jazzy Jeff and others) fits this quite well -- especially re your "have the audience understand what he is doing argument"
Haha that is a great highly expressive counter example! However, as far as versatility of sound I still think the guitar+tube amp wins as you have access to all of western music theory and techniques as its still a traditional string instrument.
There have been some interesting keyboard input devices coming out which allow for more expression than normal piano keys, using a sort of hack to the MIDI system called MPE - MIDI Polyphonic Expression. For example the Seaboard Rise or the Osmose. Depending on the instrument it's possible to do per-note pitch bends, change pressure while holding notes, perform vibrato etc. Visually the physical movement is not as interesting as electric guitar though, so yours probably still wins.
You could argue that it's one of the most versatile instruments, sure. "Greatest" is completely subjective.
But is it one of the most versatile instruments? You can do signal transforms with any kind of audio input, although it's done more with the electric guitar than any other instruments.
I would say it in practice, it has the most versatile sonic profile.
A modular synth is more versatile in terms of enumerated signal transformations. Its the ability to be expressive with those signal transformations that makes the guitar+tube amp what it is.
With the right interface, I think the synth can be more expressive. Look at the Haken Continuum or ExpressiveE Osmose - both can be used with something like the Expert Sleepers FH-2 to get MPE data to the modular.
I do see your point, and agree the amount of articulation you can do with guitar is hard to beat, but I do think a synth can win, if the setup is built for it.
Synths with mod wheels are the bomb, I used to have a roland that had a pitch wheel for bends and then push it for tremolos, vibratos and such, and way more voices, envelopes etc and that was a few decades ago and I'm sure that nowadays guitars are not going to compete except at one thing, making guitar sounding noises, you can get guitary sounds but somehow they come off to me to be too clean and lack the slop that various fingerings produce lol
> All other electronic instruments, with the one exception being the Theramin, have a fundamental problem with human expression. There is an unsolvable disconnect between what the performer's actions and their audience.
Electric bass? Heck, even in synthesizers, you have the EWI or the Haken Continuum.
Guitar (and bass) are obviously and far and away the most successful, but it does a disservice to a number of wonderful inventions to say they're the only ones. Just look at what the Japanese band T-SQUARE does with the EWI to see people innovating at the edges.
I watched Wayne Coyne of the Flaming Lips do something similar with some kind of "I don't know what" controller, it was some kind of input in his microphone stand. As he moved it around, the sound and projection changed.
I remembered learning about similar MIDI controllers when I was in school.
Imogen Heap created a set of gloves that transform finger flexing and wrist movement into midi signals you can use in whatever way your performance software allows.
I feel like the synthesizer--CMI Fairlight, Moog anything, Synclavier, PPG Wave, and just the general concept of modular synthesis--are pretty staunch competitors. Yours is certainly a fun and fair take, and arguably the electric guitar+tube amps birthed so many genres (blues, soul, funk, rock, punk, metal, etc) where as synthesizers remained pretty niche with their contribution to experimental music and pop music, mixing in with rock funk and disco, and the titan of EDM that grew out of that.
I generally reserve the word electronic to mean something with a microcontroller or discreet logic components. Electronic guitars exist, but they're basically differently shaped keyboards.
I often lament the lack of other electric instruments.
Synth music elevated electric bound tones to anything ever heard.
I remidn you that most of the rock and roll and rock music was about speed and mimicking the sound of a rumbling car engine, as it was a symbol of the freedom in America, being able to run away from your toxic communities to find yourself better anywhere else.
That was the message for the young with rock and roll: a speedy engine for your ears.
Electronic music was like replacing a car with UFO evoking you a space travel.
With the progressive subgenre of techno music you got the same feeling, but with no subtle hints. Heck, one of the most known songs in Spain ever, "Flying Free", literally remixes the sounds of drifting cars between the melodies, making the listener really happy in a very direct way as tons of youngs in the 90's got into the outskirt night clubs... by car. So they felt as driving an infinite highway rave with no end for days.
The amusing thing (to me at least) is that while the DX7 gave users almost infinite options as to how they could create and shape sounds, if you know what to listen for you'll hear the E PIANO 1 and BASS 1 presets an about half of all mid 80s hits. Turns out when they gave musicians a tool with immense flexibility, many of them still chose to use two of the (admittedly great) preset sounds.
The DX-7 FM synthesis opened the door to a pretty narrow but interesting range of sounds, bells and brass, which people loved and it was a ripsnorting success for a time, but it didn't displace subtractive analog synths and people aren't exactly playing FM synthesizers any more, while they are now heavily back into analog subtractive. of course there are also romplers and samplers etc. and those can achieve sounds that FM did, but it's hard to call the DX-7 any type of be-all end-all.
>"All other electronic instruments, with the one exception being the Theramin, have a fundamental problem with human expression. There is an unsolvable disconnect between what the performer's actions and their audience."
Look at Roli Seaboard, it has insane amount degrees of freedom / expression
Hi! I work at IEEE Spectrum and there's no way an LLM wrote this. We have a pretty strict Generative AI use policy (bottom of this page https://spectrum.ieee.org/about). I'm guessing this is from writers using actual writing techniques that Gen AI stole from...
I took my introductory college writing classes at a college I can’t name-drop without sounding like a jerk, which also did a bunch of LLM research over the years. We used a TON of em dashes in our writing. It’s no mystery, to me, where that stylistically prevalent quirk comes from. I’ve definitely been accused of being an LLM bot.
I was speaking with my 14 year old nephew via messaging last month. It was about a deep topic, synthetic consciousness. He wrote such an intelligent reply that I asked him: hey, was this from an LLM? He was insulted. I did research with his parents and found out that 90% no, he's just a very smart kid.
Is there a name for this this mode of confusion yet?
Indeed. Along the same lines, the recent "humans parading as agents" on moltbook story made me think... what is the inverse of the goal of captcha? That's impossible practically, right?
It's because there's clearly a near-1:1 ratio of input to output. I also noticed some LLMisms, and I suspect the author may have ran the text (perhaps in the form of a large number of bullet points) through an LLM. But because he's using the LLM to clean instead of multiply, it's still worth reading.
Probably similar to what I do with my papers and resumes, I write them myself then throw them through LLMs for suggestions and corrections, manually reviewing the output.
LLM-isms are tolerably bad. LLM's narrative ability is intolerably terrible. As others said, because a human actually wrote the overall narration for this, it was still compelling to read. The mistake would be skipping a well-narrated and thoughtful article just because of a few bad LLMisms.
I think LLM's lack of "theory of mind" leads to them severely underperforming on narration and humor.
Ironic because IEEE Spectrum has an anti-LLM policy. So your complex about LLM writing styles has indirectly caused you to stop supporting genuine prose.
Seriously there's no LLM stuff in here. Only emdashed which were used in journalism decades before AI was even a thing.
I feel for you, because moving forward more and more interesting and substantious articles will be written with llm-isms, either because LLM was used directly in writing or because the authors absorbed the style.
The way this article was written, is the standard way these kind of US pop science articles have always been written. It's LLM that absorbed that, not the opposite.
For a better example of the guitar as a synth like feedback device listen to robert fripps solo on heroes by bowie. He used markings on the studio floor to achieve the desired tone.
I've often marveled at the success many guitar players had with experimental electronics - Hendrix, EVH, Les Paul, Brian May, Jack White, and Tom Scholz (special case, of course) are just a few examples.
The podcast "History of Rock in 500 Songs" (full disclosure: I am a devout, slavering fan) provides these on the regular. I was actually smiling when I heard a fairly new song that attempts a really flat, fuzzed out sound because it made me think, "Buddy Holly invented that by accident with a broken speaker". One of the episodes on The Who goes into the Marshall behind Marshall amps in similar detail.
I suppose if I were going to recommend a single episode to Hacker News though, it would be https://500songs.com/podcast/episode-146-good-vibrations-by-... which begins with at least a half hour on the amazing (if not happy) life of the guy who invented the Theremin, Lev Sergeyevich Termen.
This is why I feel the recentish (last 10-15 years) shift in decoupling CS curricula from EE and CE fundamentals in the US is doing a massive disservice to newer students entering the industry.
DSP, Control Engineering, Circuit Design, understanding pipelining and caching, and other fundamentals are important for people to understand higher levels of the abstraction layers (eg. much of deep learning is built on top of Optimization Theory principles which are introduced in a DSP class).
The value of Computer Science isn't the ability to whiteboard a Leetcode hard question or glue together PyTorch commands - it's the ability to reason across multiple abstraction layers.
And newer grads are significantly deskilled due to these curriculum changes. If I as a VC know more about Nagle's Algorithm (hi Animats!) than some of the potential technical founders for network security or MLOps companies, we are in trouble.
I came into a CS and math background without CE or EE, and took two dedicated optimization courses (one happened to be in a EE department, but had no EE prereqs), as well as the optimization introduced in machine learning classes. To be honest a lot of the older school optimization is barely even useful, second-order methods are a bit passe for large scale ML, largely because they don't work, not because people aren't aware (Adam and Muon can be seen as approximations to second-order methods, though, so it is useful to be aware of that structure).
Isn't Nagle usually introduced in a networking class typically taken by CS (non-CE/EE) undergrads?
Just because EEs are exposed to some mathematical concepts during their training doesn't mean that non-EEs are not exposed through a different path.
> Isn't Nagle usually introduced in a networking class typically taken by CS (non-CE/EE) undergrads
Networking, OS, and Distributed Systems is increasingly treated as CompE or even EE nowadays in the US.
> Just because EEs are exposed...
That's the thing - I truly do not believe that EE and CS should be decoupled, and I believe ECE as a stopgap is doing a disservice to the talent pipeline we need for my verticals to remain in the US, especially when comparing target American CS and EECS programs to peer CEE, Indian, and Israeli CS programs [0].
There is no reason that a CS major should not be required to take a summary circuits, DSP, computer architecture, and OS fundamentals course when this is the norm in most CS programs abroad. Additionally, I do not see any reason for EEs and ECEs to not take Algorithms, Data Structures, and Compilers as well.
> Just because EEs are exposed to some mathematical concepts during their training doesn't mean that non-EEs are not exposed through a different path
Mind you, I'm primarily in Cybersecurity, AI/ML infra, DefenseTech, and DeepTech adjacent spaces - basically, anything aligned with the "American Dynamism" or Cyberstarts thesis.
From what I've seen, the most successful founders are those who are able to adeptly reason and problem solve, but are also able to communicate to technical buyers because you are selling a technical product where those people make the decision.
Just because an approach isn't useful today doesn't necessarily imply it isn't in the future and being exposed to those kinds of knowledge and foundational principles makes it easier for one to evaluate and reason through problem spaces that are similar but not necessarily the same - for example, going to the Nagle's example - this was a bog standard networking concept that has now become critical in foundation model training because interconnect performance is a critical problem which can impact margins.
A lot of foundational knowledge is useful no matter what, and is why we fund founders and hire talent at competitive salaries.
Muon is much more sophisticated than Newton's method. Neural networks have started to borrow techniques from statistical mechanics, and various branches of maths like invariant theory that were previously rarely used in engineering. CS is not dumbing down; its needs and focus are changing.
I've never needed or benefited from most of the EE curriculum. There is an opportunity cost in learning things you don't need.
I graduated in 2020 and I took a circuit design class and was taught Nagles algorithm. I guess I could have learned more but I thought the degree was packed enough with enough when you consider all the different parts of it, from the math to systems programming to ML stuff.
This is a terrible article. In the first subplot, there is no explanation of what v(b1) and v(c2) are. The -8 on the on y axis (amplitude) looks like an upside down 8.
Further down there is a sentence: "First, the Fuzz Face is a two-transistor feedback amplifier that turns a gentle sinusoid signal into an almost binary “fuzzy” output." But the figure does not match this - there is no "gentle sinusoid" wave shown on the first fuzz face plot.
Art and engineering are both constrained optimization problems - at their core, both involve transforming a loosely defined aesthetic desire into a repeatable methodology!
And if we can call ourselves software engineers, where our day-to-day (mostly) involves less calculus and more creative interpretation of loose ideas, in the context of a corpus of historical texts that we literally call "libraries" - are we not artists and art historians?
We're far closer to Jimi than Roger, in many ways. Pots and kettles :)
That's stretching the term to the breaking point, for me. Is there some evidence of systematic analysis of component parts? attempts to model elements of the problem? data gathering and data analysis? simulation? Intentional application of principles of physics or some other pure domain to a real world problem?
Artistic endeavors come from lots of places, not just people with an analytical mindset. Historically those two are seen as opposing tendencies, which I think is unfair, but it points to the importance of intuition and navigating perception and emotion for artists.
Hendrix reportedly discovered feedback by walking away from a cranked amp. The guitar just kept sustaining on its own. What followed was years of empirical system identification: learning how body position, pickup selection, and guitar-to-amp distance affected feedback character. No transfer function, just iteration. That's a valid engineering methodology.
Any guitarist in a 1940s big band would have a big hollowbody guitar and an amp. That combination is incredibly prone to feedback. Everyone worked to reduce feedback and avoid it. That's what I do with my hollowbody when I play with a big band. It's the first thing that happens when you turn up.
Hendrix did not "discover" feedback, and in fact he did not discover the musical uses of feedback - you can hear it in BB King records that predate Hendrix, where feedback makes his notes "sing."
What Hendrix did was turn feedback into an intentional musical creation that he treated as a melodic voice.

Crazy example of when everything is AI generated, even the code referenced in git repo (refer to commit 3d733ca), and actually interesting and "new" in a way...
I’m curious because to tell you the truth the novelty struck me as similar to comparisons I’ve toyed with using LLMs on my own. The AI-generated logic between comparing two dissimilar things is too sterile for my liking.
I understand that this is appearing in technical publication, but for some reason that invites even further scrutiny on my behalf.

Thanks (I think).
The imagery of 1969, I remember it well. The Vietnam war was the first war that was televised. Everyone would watch the nightly news at 6:30 pm (take my word for it) and hear the choppers, gunfire and real life screams of people.
I thought it was sheer genius that Hendrix was able to subtly bring that into the national anthem which made it resonate so well with those purchasing his music. But without that background reference I never supposed that younger generations would hear it entirely differently.
Maggot Brain begins with on-the-nose apocalyptic imagery, but ends with a release and rebirth. One day, the fighting stops.
I've not listened to that song much at all. I am however obsessed with Machine Gun which has all those elements and more. Maybe I'll have a re-listen to SSB.
The first time I had an amp distorted and loud enough to cause feedback (if I wanted to) at band practice was the most magical day of my life.
I had heard it a lot in punk and pop-punk to create swells. I improvised my still-favorite solo that day.
I wonder if tube harmonics modeled by solid state settings has shaped music. Of course it has; music from that era is instrument-oriented.
The discovery of feedback tones and the resulting incorporation in the musical experience — a three hour warm bank of tubes turned up to the limit with a maxxed out savant unlocking new realms of sound.
I think I recall reading about Hendrix that he tried to emulate the sounds of cartoons with his guitar, and then when he was in the army he did the same with trying to reproduce the sounds of fighter jets. Not sure if urban legend, but cool origin story.
Strange article. Even though I do like music and engineering.
>Electromagnetic pickups—(...)—fixed the loudness problem. But they left a new one: the envelope
Was it really a problem to be solved? Good tube amplifiers already existed back then. Clean guiar tone was not something frowned upon.
>Hendrix’s mission was (...)
>His solution was (...)
I don't think Hendrix was on a 'mission' to solve engineering puzzles at all. He was just experimenting, as an artist.

1,000,000%. Guitar is one of those hobbies where people mythologize and build elaborate hagiographies around players they like and the gear that they used. Hendrix was a generational talent but I highly doubt he was sitting around enumerating problem statements and systematically exploring solution spaces. The Fuzz Face was one of like four dirtboxes available during that time so he chose that one. He flipped a guitar upside down because he could source one more easily than a lefty model. He leveraged feedback because he discovered it naturally and realized that he could make it sound totally badass.
The man clearly had a vision and executed it but his decisions were pragmatic, not the product of grand technical reasoning. It reminds me of the student who wrote a bunch of authors and asked to what degree they were conscious of the themes and symbolism in their work [1]. Many were not - as it turns out English teachers often put the cart before the horse. This is the rock and roll version of that.
I can't knock the article though as it has a lot of sound (pun intended) analysis in it as opposed to typical guitar forum dreck about NOS tube and hand-wired turret board magic.

> He flipped a guitar upside down because he could source one more easily than a lefty model.
I've read that he claimed he played a right-handed guitar upside down because his father was superstitious and didn't like him doing things left-handed, so he'd play a right-handed guitar upside down most of the time and flip it over when he needed to play in front of his father. (I'm not sure why he didn't play a lefty guitar upside if that was the case, but I could imagine that the availability might be relevant like you mentioned, or maybe his father was familiar enough with guitars to be able to recognize a left-handed one and figure out what was going on, or maybe because he was better left-handed he could play it upside-down well enough but due to not being right-handed he would have found it more difficult to play it in the non-standard way).
Yes. The article had about the same effect as explaining a joke.
Interesting factoid: modern guitar effects typically have their input jacks on the right-hand side, and output jacks on the left. In this article's guitar rig diagram, the jacks are reversed, but this is accurate: back then, for whatever reason the jacks were reversed on each of these pedals. Modern reissues of the round-enclosure Fuzz Face pedals preserve this pattern despite the reversal of industry trends.
It does seem weird, I’d expect signal to flow from left to right, as English is written, as a number line is drawn, from -x to 0 to +x
> Electric guitars attack hard, decay fast, and don’t sustain like bowed strings or organs.
Since the 1980s, we have had the "Sustainiac": an active circuit installed in the electric guitar along with a "reverse pickup" which is energized in order to excite vibration in the strings.
With this device, at the flip of a switch, you get indefinite sustain on any note on the neck, at any volume, distortion or not --- even if the electric guitar is not plugged into an amplifier at all, and just heard acoustically.
The best implementations of this have a three way harmonic switch. You can choose between excite the fretted (or open) note itself (fundamenta a.k.a first harmonic), an octave above it (second harmonic) or a higher harmonic still.
You can be sustaning the given note, and then at the flip of a switch, it will fade over to the higher harmonic.
YouTube videos of this in action are worth checking out.
Here is one:
https://www.youtube.com/watch?v=LZwPPGsxY6g
If you don't want to or can't install a Sustainiac pickup, you can get a much cheaper handheld one-string "E-Bow" that does the same thing. It's not as easy to use as a Sustainiac and you can't also be playing with the whammy bar unlike with a Sustainiac, but you can get it to do tricks a Sustainiac can't do: see the "spiccato" section in https://www.youtube.com/watch?v=b0V3pzxma-8
I've also managed to make an E-Bow work with a steel-string acoustic guitar (but only on one string IIRC).
I strongly believe that if you set aside genre preferences the solid body electric guitar coupled to a tube amplifier is objectively the greatest electronic instrument ever created.
All other electronic instruments, with the one exception being the Theramin, have a fundamental problem with human expression. There is an unsolvable disconnect between what the performer's actions and their audience.
See: https://www.scribd.com/document/55134776/48787070-Bob-Ostert...
With an electric guitar you get the physicality and dynamism of an acoustic instrument with the complex timbres and extended technique possibilities of an electric/electronic instrument.
There are complex and musically significant feedback loops occurring across many dimensions that lead to extremely complex transformations of timbre via both traditional music theoretical techniques and the physics of a tube amplifier combined with an inductive load (the guitar pickup).
Its really crazy how much more dynamic and complex this can be then even a highly sophisticated modular synthesizer or whatever. Even the way you over load the power supply in a tube amplifier can be manipulated on the fly to enhance and transform timbre.
Then on top of all that it is so incredibly physical that a performer like Jimi Hendrix can manipulate these systems and have the audience intuitively understand what he is doing. Never in a million years would THAT be possible with any other electronic instrument.
The reverse example of this is musicians who play techno with analog instruments, like Pipe Guy, Basstong, and Meute[0][1][2].
There are always some people who get extremely defensive whenever I say that techno didn't click for me until I heard this kind of "techlow" music. Specifically about the part where I think that the reason is also a human expression problem, because of limitations imposed by the electronic media used.
EDIT: having said that, I don't think I would agree with your premise, because it is colored by a subtle form of survivor bias. None of us remember what it's like to not know electronic guitars or what they sound like, so claiming "the audience intuitively understands what Jimmy Hendrix is doing" is like saying everyone "intuitively understands" their native language. On top of that there's nothing about the workings of an electronic guitar that wouldn't in principle work for something like an electronic violin or whatever.

I guess the part people don't like hearing is the implication techno is somehow not expressive. I'm not sure that it lacks expressiveness, but it is certainly more "controlled" than traditional music. When I first heard techno as a teenager in the 90s, my mind was blown. I remember exactly where I was the first time I heard Underworld [1], Photek [2], and Autechre [3]. I think I was attracted to these sounds _because_ they were so different. I think it's hard for electronic music fans like myself to accept the idea that it isn't expressive _because_ it is so different. Isn't it just a different kind of expression?
Still, people like what they like. I'm glad you found a version of dance music that works for you. I've long since moved on being judgmental about people's musical tastes. I think it's just wonderful that music exists at all!

Legends Never Die - Leagueoflegends + Ethnic Instruments by Belle Sisoski [1]. And no, I've never played LoL, I probably never will, and I haven't seen that series based on it (Arcana or something?) either.

For electric violin, I love Ed Alleyne-Johnson [3]. Never seen him live (I'm not from UK) but I own a couple of his earlier works. It reminds me of that time when my dad was in his final years of his lives, and when he finally passed away. Makes me cry every time.

Great recommendations. Throwing Klangphonics in the ring even though they use electronic instruments as well
https://www.youtube.com/watch?v=bixtQAq2LzE
Nice addition! First time I heard of them and I'm liking what I'm hearing so far.
And just to clarify: I don't dislike electronic instruments. I just think that on some subconscious level the human brain can detect other humans playing a live instrument. Like there's something "embodied" in the sound that is likely missing from a pure electronic instrument. And I needed that element to "unlock" access to techno.
Yep, there's a reason we have the industry term "humanization" in sound design, composition and arrangement.
Tons of work has been done on various modes of humanization by trying to parameterize and modulate these aspects over time. Timing accuracy, velocity variance, chance, etc.
A well-played instrument certainly feels like someone speaking and expressing themselves to you. There are attempts to capture this with MPE instruments such as the Osmose, or Imogen Heap's MiMU gloves.

Hmmm, I disagree, having played electric and acoustic guitars for over two decades and begun learning piano and synths for the first time in 2025.
For one, you can’t easily play two melodies simultaneously across several octaves, using both of your hands, with an electric guitar.
Stringed electronic instruments do have their advantages, but so do the others. Each music making thing has its place in the spectrum.
Two books that have helped me greatly in my musical life, in case people haven’t heard of them, are The Listening Book, and Bridge of Waves, by W.A. Mathieu.
> There is an unsolvable disconnect between what the performer's actions and their audience
Is that really true though? If I watch a cellist play I can pretty clearly see all the things they are doing and it will correlate neatly to the timbre of the sound.
Secondly I think it's important to note the tube amp and the guitar are seperable, and I don't think that their connection is particularly magical. I can reamp a sound from my synthesizer (or maybe a keytar?) into a guitar chain, and if I manipulate the mic and other controls in the same way I might manipulate the pickup, I can also get all manner of interesting feedback effects. My inputs will have different harmonic characteristics of course, and the tube amp's effects are mostly transformations of harmonics; you'll still get some cool tones and they will be subject to a lot of the same rules as if a guitar was being played.
They're talking about electronic instruments there. The comment is about how electronic instruments don't generally match the physical expressiveness of acoustic instruments (like the Cello).
I'm talking about electronic instruments how they are deficient in expressiveness compared to your cello example.
> Secondly I think it's important to note the tube amp and the guitar are seperable, and I don't think that their connection is particularly magical.

The story is not quite so simple. Your synthesizer is going to have a buffered output so it wont have the complex impedance loading interactions with the amplifier as the guitar pickup.
This is actually critical to how early distortion effects such as the classic Fuzzface work and imo is essential for the kind of complex timbres you can produce with a guitar + tube amp.
In fact you can take an electric guitar, put a buffer pedal in the chain between your fuzz pedal and amp and completely destroy the ability to produce wild feedback and distortion.
So... use a reamp box to make it hiZ again?
I'm a guitarist, but there's nothing particularly magical about a high impedance signal, other than they tend to lead to noise and make really obnoxious things matter, like how low capacitance your cable is. Also, a TON of modern guitars are low(ish) impedance out because they use active pickups.
The pedals and system being dependent on the high impedance was always a bug, not a feature, and make the setup incredibly dependent on variables that really wouldn't be that hard to just buffer then recreate deterministically. Like, if your pedal should react to that impedance just buffer the front, put a big inductor (or a transformer using only half, or, - and I've actually seen this - just a whole guitar pickup) in the pedal. Then you're not dependent on the pickups of the guitar or the capacitance of cable or anything else and you can make sure the effect sounds good regardless of pickup type.
> So... use a reamp box to make it hiZ again?
That is going to be something like a transformer to step down your line level signal and some series resistance to match the load to help drive the amp.
An actual coil pickup has reactive impedance that is frequency dependent and will result in a more complex interaction between the devices.
> The pedals and system being dependent on the high impedance was always a bug, not a feature
Sure if you think like an engineer, but everything you are complaining about is what allows someone like Jimi Hendrix to do what he did with a guitar.
they're comparing an electric guitar to electronic instruments, like midi keyboards. An electric cello would be the same thing as an electric guitar in this context.
Great argument -- but I'd also counter that "the turntable" (i.e. in the hands of experts like Q-Bert, Craze, Rob Swift, Jazzy Jeff and others) fits this quite well -- especially re your "have the audience understand what he is doing argument"
Haha that is a great highly expressive counter example! However, as far as versatility of sound I still think the guitar+tube amp wins as you have access to all of western music theory and techniques as its still a traditional string instrument.
Oh I'll fight you there. Turntable wins because you have access to LITERALLY ALL RECORDED MUSIC EVER :)
There have been some interesting keyboard input devices coming out which allow for more expression than normal piano keys, using a sort of hack to the MIDI system called MPE - MIDI Polyphonic Expression. For example the Seaboard Rise or the Osmose. Depending on the instrument it's possible to do per-note pitch bends, change pressure while holding notes, perform vibrato etc. Visually the physical movement is not as interesting as electric guitar though, so yours probably still wins.
You could argue that it's one of the most versatile instruments, sure. "Greatest" is completely subjective.
But is it one of the most versatile instruments? You can do signal transforms with any kind of audio input, although it's done more with the electric guitar than any other instruments.
I would say it in practice, it has the most versatile sonic profile.
A modular synth is more versatile in terms of enumerated signal transformations. Its the ability to be expressive with those signal transformations that makes the guitar+tube amp what it is.
I'm a guitarist, but also have a modular.
With the right interface, I think the synth can be more expressive. Look at the Haken Continuum or ExpressiveE Osmose - both can be used with something like the Expert Sleepers FH-2 to get MPE data to the modular.
I do see your point, and agree the amount of articulation you can do with guitar is hard to beat, but I do think a synth can win, if the setup is built for it.
Synths with mod wheels are the bomb, I used to have a roland that had a pitch wheel for bends and then push it for tremolos, vibratos and such, and way more voices, envelopes etc and that was a few decades ago and I'm sure that nowadays guitars are not going to compete except at one thing, making guitar sounding noises, you can get guitary sounds but somehow they come off to me to be too clean and lack the slop that various fingerings produce lol
> All other electronic instruments, with the one exception being the Theramin, have a fundamental problem with human expression. There is an unsolvable disconnect between what the performer's actions and their audience.
Electric bass? Heck, even in synthesizers, you have the EWI or the Haken Continuum.
Guitar (and bass) are obviously and far and away the most successful, but it does a disservice to a number of wonderful inventions to say they're the only ones. Just look at what the Japanese band T-SQUARE does with the EWI to see people innovating at the edges.
I watched Wayne Coyne of the Flaming Lips do something similar with some kind of "I don't know what" controller, it was some kind of input in his microphone stand. As he moved it around, the sound and projection changed.
I remembered learning about similar MIDI controllers when I was in school.
Imogen Heap created a set of gloves that transform finger flexing and wrist movement into midi signals you can use in whatever way your performance software allows.

I feel like the synthesizer--CMI Fairlight, Moog anything, Synclavier, PPG Wave, and just the general concept of modular synthesis--are pretty staunch competitors. Yours is certainly a fun and fair take, and arguably the electric guitar+tube amps birthed so many genres (blues, soul, funk, rock, punk, metal, etc) where as synthesizers remained pretty niche with their contribution to experimental music and pop music, mixing in with rock funk and disco, and the titan of EDM that grew out of that.
I generally reserve the word electronic to mean something with a microcontroller or discreet logic components. Electronic guitars exist, but they're basically differently shaped keyboards.
I often lament the lack of other electric instruments.
Ahem, just two words. Yamaha DX-7.
Synth music elevated electric bound tones to anything ever heard.
I remidn you that most of the rock and roll and rock music was about speed and mimicking the sound of a rumbling car engine, as it was a symbol of the freedom in America, being able to run away from your toxic communities to find yourself better anywhere else.
That was the message for the young with rock and roll: a speedy engine for your ears.
Electronic music was like replacing a car with UFO evoking you a space travel.
With the progressive subgenre of techno music you got the same feeling, but with no subtle hints. Heck, one of the most known songs in Spain ever, "Flying Free", literally remixes the sounds of drifting cars between the melodies, making the listener really happy in a very direct way as tons of youngs in the 90's got into the outskirt night clubs... by car. So they felt as driving an infinite highway rave with no end for days.
The amusing thing (to me at least) is that while the DX7 gave users almost infinite options as to how they could create and shape sounds, if you know what to listen for you'll hear the E PIANO 1 and BASS 1 presets an about half of all mid 80s hits. Turns out when they gave musicians a tool with immense flexibility, many of them still chose to use two of the (admittedly great) preset sounds.
To be fair, a lot of that is because the DX7 (or rather, FM synthesis in general) is just absolutely arcane when it comes to programming.
The DX-7 FM synthesis opened the door to a pretty narrow but interesting range of sounds, bells and brass, which people loved and it was a ripsnorting success for a time, but it didn't displace subtractive analog synths and people aren't exactly playing FM synthesizers any more, while they are now heavily back into analog subtractive. of course there are also romplers and samplers etc. and those can achieve sounds that FM did, but it's hard to call the DX-7 any type of be-all end-all.

Look at Roli Seaboard, it has insane amount degrees of freedom / expression

I suppose you haven’t heard some really talented sitar players out there. For a traditionally non-electronic instrument, it’s got some crazy sounds.
I think you misunderstand my comment entirely. I'm not comparing electric to acoustic instruments at all.
This is one of the few articles where I noticed a bunch of LLM-isms and still read to the end because it was interesting.
Hi! I work at IEEE Spectrum and there's no way an LLM wrote this. We have a pretty strict Generative AI use policy (bottom of this page https://spectrum.ieee.org/about). I'm guessing this is from writers using actual writing techniques that Gen AI stole from...
I took my introductory college writing classes at a college I can’t name-drop without sounding like a jerk, which also did a bunch of LLM research over the years. We used a TON of em dashes in our writing. It’s no mystery, to me, where that stylistically prevalent quirk comes from. I’ve definitely been accused of being an LLM bot.
I just wanted to relate a story.
I was speaking with my 14 year old nephew via messaging last month. It was about a deep topic, synthetic consciousness. He wrote such an intelligent reply that I asked him: hey, was this from an LLM? He was insulted. I did research with his parents and found out that 90% no, he's just a very smart kid.
Is there a name for this this mode of confusion yet?
Strikes me as an opposite of the Uncanny Valley.
Indeed. Along the same lines, the recent "humans parading as agents" on moltbook story made me think... what is the inverse of the goal of captcha? That's impossible practically, right?
Schools have a strict Generative AI policy as well, and yet...
It's because there's clearly a near-1:1 ratio of input to output. I also noticed some LLMisms, and I suspect the author may have ran the text (perhaps in the form of a large number of bullet points) through an LLM. But because he's using the LLM to clean instead of multiply, it's still worth reading.
Probably similar to what I do with my papers and resumes, I write them myself then throw them through LLMs for suggestions and corrections, manually reviewing the output.
I didn't see any LLM-isms. Emdashes I guess, but I expect those in actual articles, they're only fishy in social media comments.
LLM-isms are tolerably bad. LLM's narrative ability is intolerably terrible. As others said, because a human actually wrote the overall narration for this, it was still compelling to read. The mistake would be skipping a well-narrated and thoughtful article just because of a few bad LLMisms.
I think LLM's lack of "theory of mind" leads to them severely underperforming on narration and humor.
It doesn't read like an LLM to me. What are you seeing?
I bailed, it just really kills my desire to keep reading.
Ironic because IEEE Spectrum has an anti-LLM policy. So your complex about LLM writing styles has indirectly caused you to stop supporting genuine prose.
Seriously there's no LLM stuff in here. Only emdashed which were used in journalism decades before AI was even a thing.
I feel for you, because moving forward more and more interesting and substantious articles will be written with llm-isms, either because LLM was used directly in writing or because the authors absorbed the style.
The way this article was written, is the standard way these kind of US pop science articles have always been written. It's LLM that absorbed that, not the opposite.
For a better example of the guitar as a synth like feedback device listen to robert fripps solo on heroes by bowie. He used markings on the studio floor to achieve the desired tone.
I've often marveled at the success many guitar players had with experimental electronics - Hendrix, EVH, Les Paul, Brian May, Jack White, and Tom Scholz (special case, of course) are just a few examples.
Brian May stands out even among that group (well maybe not w/ Les Paul there)

One of the episodes on The Who goes into the Marshall behind Marshall amps in similar detail.
I suppose if I were going to recommend a single episode to Hacker News though, it would be https://500songs.com/podcast/episode-146-good-vibrations-by-... which begins with at least a half hour on the amazing (if not happy) life of the guy who invented the Theremin, Lev Sergeyevich Termen.

There is art in engineering that we cannot deny.
While some try to make it as exact science, it is not, there are things you still cannot put a number on and it works ...
This is why I feel the recentish (last 10-15 years) shift in decoupling CS curricula from EE and CE fundamentals in the US is doing a massive disservice to newer students entering the industry.
DSP, Control Engineering, Circuit Design, understanding pipelining and caching, and other fundamentals are important for people to understand higher levels of the abstraction layers (eg. much of deep learning is built on top of Optimization Theory principles which are introduced in a DSP class).
The value of Computer Science isn't the ability to whiteboard a Leetcode hard question or glue together PyTorch commands - it's the ability to reason across multiple abstraction layers.
And newer grads are significantly deskilled due to these curriculum changes. If I as a VC know more about Nagle's Algorithm (hi Animats!) than some of the potential technical founders for network security or MLOps companies, we are in trouble.
I came into a CS and math background without CE or EE, and took two dedicated optimization courses (one happened to be in a EE department, but had no EE prereqs), as well as the optimization introduced in machine learning classes. To be honest a lot of the older school optimization is barely even useful, second-order methods are a bit passe for large scale ML, largely because they don't work, not because people aren't aware (Adam and Muon can be seen as approximations to second-order methods, though, so it is useful to be aware of that structure).
Isn't Nagle usually introduced in a networking class typically taken by CS (non-CE/EE) undergrads?
Just because EEs are exposed to some mathematical concepts during their training doesn't mean that non-EEs are not exposed through a different path.
> Isn't Nagle usually introduced in a networking class typically taken by CS (non-CE/EE) undergrads
Networking, OS, and Distributed Systems is increasingly treated as CompE or even EE nowadays in the US.
> Just because EEs are exposed...
That's the thing - I truly do not believe that EE and CS should be decoupled, and I believe ECE as a stopgap is doing a disservice to the talent pipeline we need for my verticals to remain in the US, especially when comparing target American CS and EECS programs to peer CEE, Indian, and Israeli CS programs [0].
There is no reason that a CS major should not be required to take a summary circuits, DSP, computer architecture, and OS fundamentals course when this is the norm in most CS programs abroad. Additionally, I do not see any reason for EEs and ECEs to not take Algorithms, Data Structures, and Compilers as well.
> Just because EEs are exposed to some mathematical concepts during their training doesn't mean that non-EEs are not exposed through a different path
Mind you, I'm primarily in Cybersecurity, AI/ML infra, DefenseTech, and DeepTech adjacent spaces - basically, anything aligned with the "American Dynamism" or Cyberstarts thesis.
From what I've seen, the most successful founders are those who are able to adeptly reason and problem solve, but are also able to communicate to technical buyers because you are selling a technical product where those people make the decision.
Just because an approach isn't useful today doesn't necessarily imply it isn't in the future and being exposed to those kinds of knowledge and foundational principles makes it easier for one to evaluate and reason through problem spaces that are similar but not necessarily the same - for example, going to the Nagle's example - this was a bog standard networking concept that has now become critical in foundation model training because interconnect performance is a critical problem which can impact margins.
A lot of foundational knowledge is useful no matter what, and is why we fund founders and hire talent at competitive salaries.

Muon is much more sophisticated than Newton's method. Neural networks have started to borrow techniques from statistical mechanics, and various branches of maths like invariant theory that were previously rarely used in engineering. CS is not dumbing down; its needs and focus are changing.
I've never needed or benefited from most of the EE curriculum. There is an opportunity cost in learning things you don't need.
I graduated in 2020 and I took a circuit design class and was taught Nagles algorithm. I guess I could have learned more but I thought the degree was packed enough with enough when you consider all the different parts of it, from the math to systems programming to ML stuff.

Further down there is a sentence: "First, the Fuzz Face is a two-transistor feedback amplifier that turns a gentle sinusoid signal into an almost binary “fuzzy” output." But the figure does not match this - there is no "gentle sinusoid" wave shown on the first fuzz face plot.
Base 1, collector 2?
The original title: "Jimi Hendrix's Analog Wizardy Explained."
> and the component was the Octavia guitar pedal, created for Hendrix by sound engineer Roger Mayer.
So, Roger was the engineer. And, Jimi was the artist.
Art and engineering are both constrained optimization problems - at their core, both involve transforming a loosely defined aesthetic desire into a repeatable methodology!
And if we can call ourselves software engineers, where our day-to-day (mostly) involves less calculus and more creative interpretation of loose ideas, in the context of a corpus of historical texts that we literally call "libraries" - are we not artists and art historians?
We're far closer to Jimi than Roger, in many ways. Pots and kettles :)
We should not call ourselves engineers - it's a massive insult to actual professional engineers.
Speak for yourself, some of us value and incorporate both science and methodology into our craft, and adhere to a system of ethics.
Nice article, but that the signal chain in the top image doesn't match the signal chain described in the text annoys me more than it should.
It's also a standard right handed strat, which seems like an oversight for a guy famous for playing with a right handed strat flipped upside down.
Anyone doing something artistically great is engineering in some way. The Renaissance painter, the ableton producer. It all involves mastery of tools.
That's stretching the term to the breaking point, for me. Is there some evidence of systematic analysis of component parts? attempts to model elements of the problem? data gathering and data analysis? simulation? Intentional application of principles of physics or some other pure domain to a real world problem?
Artistic endeavors come from lots of places, not just people with an analytical mindset. Historically those two are seen as opposing tendencies, which I think is unfair, but it points to the importance of intuition and navigating perception and emotion for artists.
> Is there some evidence of systematic analysis of component parts?
Music theory, Nashville notation
> attempts to model elements of the problem?
Ditto
> data gathering and data analysis?
Listening to a wide variety of music and understanding what make a genre a genre
> simulation?
Cover songs, writing to a style
> Intentional application of principles of physics or some other pure domain to a real world problem?
Literally sound engineering
quite the stretch
Fascinating
"A groove engineer baby"
Hendrix reportedly discovered feedback by walking away from a cranked amp. The guitar just kept sustaining on its own. What followed was years of empirical system identification: learning how body position, pickup selection, and guitar-to-amp distance affected feedback character. No transfer function, just iteration. That's a valid engineering methodology.
What??? Where did you get this idea?
Any guitarist in a 1940s big band would have a big hollowbody guitar and an amp. That combination is incredibly prone to feedback. Everyone worked to reduce feedback and avoid it. That's what I do with my hollowbody when I play with a big band. It's the first thing that happens when you turn up.
Hendrix did not "discover" feedback, and in fact he did not discover the musical uses of feedback - you can hear it in BB King records that predate Hendrix, where feedback makes his notes "sing."
What Hendrix did was turn feedback into an intentional musical creation that he treated as a melodic voice.
Jimi on the radio is my shorthand for bad economic times. Happened in 2007 and he's playing on the airwaves now
Interesting economic indicator. But isn't Jimi playing on the radio all the time somewhere?

Crazy example of when everything is AI generated, even the code referenced in git repo (refer to commit 3d733ca), and actually interesting and "new" in a way...
There’s a git repo associated with this article?
I’m curious because to tell you the truth the novelty struck me as similar to comparisons I’ve toyed with using LLMs on my own. The AI-generated logic between comparing two dissimilar things is too sterile for my liking.
I understand that this is appearing in technical publication, but for some reason that invites even further scrutiny on my behalf.
Please share more reasons behind your suspicions.
