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.
Star Spangled Banner was incredible. The way you can hear the machine guns, choppers, sirens, screaming in agony… that was a masterpiece.

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.
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.
