I’m not reading a short at the output now, but the pedal operates the same way. That doesn’t make sense to me. If the short caused the problem, then it would be fixed now. That means it was shorted, but that there is also something else going on. I suspect maybe the B100k pot, since that controls the volume when in bypass, but I am losing interest in this pedal. I’ve never bought into the Klon myth, and only built this as a “blind date” pedal: to see how I got along with it. It sounds good (when the jacks are out of the case), but it’s just an OD…Have you traced all connections from the output to ground? If you've ruled out the switch and the jack, there's a short on the board.
