Finished Hamonic jerkulator, squeeling in max and min gain.

The problem is that when gain is set full or min. position, pedal starts to feedback heavily. I used clipping diodes mod in this build, but I used 1N4148 in place of germanium diodes. Sound is otherwise great. here is the link for diode mod. http://www.home-wrecker.com/harmonic.html

I found this topic. http://www.diystompboxes.com/smfforum/index.php?topic=8351.0 should the resistor that Tim is suggesting go before or after the input cap.

Well I fixed the squealing by changing the 22uf cap to 47uf. This thing really nails Jeff Becks Blow By Blow fuzzy kind of sound.
