I found some old notes of mine on doing a DPDT true bypass
foot switch on a wah pedal. I haven't done this in quite a while so
hopefully my old notes are correct. Let me know if you find any errors.
The in and out are the two jacks. The connections are the jack tips. I had
to add a new wire from the switch to the input jack. Otherwise all other
connections are just re-done from existing wires.
My notes say this: Unsolder the input jack tip wire. It goes from the input
jack to the circuit board and joins another wire there, usually green,
sometimes orange.
The right leg of the wah pot has a black wire that goes over to the circuit
board. Leave it alone, it is ok where it is.
Other than that, just follow the drawing and pray that it works.
