when I engage the pedal and cut the volume full up then my output is the same loudnes as the bypass.. I think that's because the drive would normally add more volume when working with the vol knob. The pots are wired in the right spots. When I was soldering I know on a few of the spots that ground to the board, my solder was kinda large. But that's what it's grounding to so I didn't think that would be a problem.
