I was just thinking about the feedback modification.
Instead of having a 500k pot in series with the audio, why not having a pot wired as a normal volume pot?
That is one end to the audio out, one end to ground, and the wiper to audio in. With a pot value of 20k or so.
And when having it turned all the way down, the input is automatically grounded.
Has ayone tested this?
