I got a non working pedal from a friend and I am attempting to rewire it since the original wiring is messed up pretty badly. I have found a reference for the wiring, however I have a question. There are two switches on the JEN: one is a toggle DPDT and the second was originally a DPST footswitch.
When looking at the attached diagram it is clear that on SW2 the middle legs (where WAH-IN & the input jack are connected) are the common soldering lugs. On the upper switch, SW1 it seems that the switching is not "horizontal" but rather vertical otherwise the wah output will never be connected to the output switch. Is this correct?
