Don't know whether this anecdote is true, but:
B.B.King once asked Hendrix something like:
"Where do all these sounds [of his Strat,
and stuff] come from?" Hendrix had replied:
"I don't know!"
Perhaps sometime in the 80's or 90's, Mike
Bloomfield, or some such guy, told on a
TV documentary, that he still hasn't figured
out how Hendrix created some of the weird
sounds without that much effect gadgetry
(just Octavia, fuzz-box and wah-wah, in
addition to creative use of feed-back?).
I've often thought if it was possible that
Jimi's intensive emotions during playing
somehow could "distort" the sounds without
his conscious effort to do so... naah!
