It can be confusing wiring wahs or pedals in wah shells cause the pots orientation is kinda backwards since you're looking at it completely different then in a normal enclosure.

I need to swap it and wanted make sure I understood the right way to do it. I actually did the sweep knob and the switchable input cap from the Modded Crybaby layout. Probably should have posted on that thread instead.
