My board input/output leads to the switch are on the sides of the board for normal operation of the switch. Can anyone who is familiar with the pcb layout tell me how to jumper the connections as to bypass the volume/wah switching mechanism? I have jumpered all of the volume mod components but, I am having trouble following the layout near the top of the board where the leads go to the switch. The layout is a pdf so I am afraid I cannot post a pic. Below is the http address to the wah layout pdf.
Thanks

If you've removed the 4k7, 220K (both) resistors, and the .22 cap, then all you do is just not wire in the switch at all (just don't put any wires to the switch pads at the top of the board).

Thanks Nish,
Oh, now I see that the 4.7uf cap just before the vol/wah switching should go to ground. Before, I thought it fed back into the circuit. The wah seems easy to mod because of the low part count and the array of components which affect the sound. I just seem to have trouble tracing the layout due to all the components which feed back into the circuit.
Thanks again

I have two leads on my inductor. Which of the four outer pads should the two leads be soldered to?
You must connect the inductor each lead to each trace, you'll see that each trace has four pads, but there are only TWO traces (only two circuit nets). The pads are there to fit a few different inductors/transformers.
