i've heard the subject in passing.........
through experimentation with a friend we tried our two amps side by side.
his amp was a YB-1 Traynor Tube amp from '67.
mine was a 2003 Mesa Boogie F-100
we put a distortion pedal through the traynor and played a chord. we let it ring out and waited for the feedback to come through. it was a harsh note that came out and it sounded dissonant.
we did the same thing through the boogie and the feedback that came out was resonant. not only that, it was in key with the chord, either the third, fifth or unison. but the amazing thing was that no matter what chord you played, even semitones up, the feedback would always hone in on the right key and match the chord.
is that "even and odd harmonics"?
if not what is it? and then what's the explanation of even and odd?
the F-100 ran 4 6L6's and 6 12ax7's
the traynor had 3 12ax7's and two larger tubes (larger than 6L6)
i don't think the F-100 had a rectifier in it either.
so many questions, so little time.
the next question will be about....... speaker phase?
