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.

  In a sluggish economy
  Inflation, recession
  Hits the land of the free
  Standing in unemployment lines
  Blame the government for hard time
  
  We just get by
  However we can
  We all gotta duck
  When the shit hits the fan

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.
