I am working on a dunlop JH1 wah and have come to a point where I am beating my head against the wall. When you click on the wah and rock the pedal to mid position it starts to feedback and if you go all the way back to the bass position it starts to howl. Now I have changed the pot , a brand new Dunlop hot potz, have tried differant inductors, changed about every cap and resistor on the board. Changed transistor pairs twice (5089 first time, 3904 the second time) . Using an audio probe the signal comes through the input buffer ok but on the 1st stage tranny it starts to howl. Any ideas here would be greatly appreciated. I am missing something. :thanks5qx:
