Default Why don't these signals null?

OP, you got a -30 dB to -50 dB result which is very good.

There are bound to be slight differences in room noise between the two takes. Or a window curtain moved slightly.


All recordings are close-miked, so room noise is minimal, and the recordings
are short(ie. approx. 10 secs). More importantly, if room noise were a
factor, the clean guitar recordings would not have nulled.


What does the residual sound like?

My best guess is that distortion introduces characteristics that are random
to a degree.


What do you mean by "distortion?" Because there are a number of different
things you could mean by that.
