Wah mod gone awry

[ethrbunny]

I did a mod to my GCB-95. I think it came from geofex. In any event Im getting radio now - but only when the pedal is rocked forward. Tilting it backward makes the radio sound go away.

What did I do wrong?

I did the same thing the other day w mine- chk you transistors and orientation, solder links, and make sure its grounded good.

did you change the resistor on the input of the circuit. thats there to get rid of RF interference and if you decreased it you may have done so by too much
