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.

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.

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 ...

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.

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.

> 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.
