I'll give you that, those dual-gang pots are always the problem in a troubleshooting thread.
I suppose if enough folks are against the board mounted jacks I could whack that entire chunk off of the PCB and use pads instead, but with board mounted jacks the entire assembly should lift out of the enclosure easily and be fully functional on the bench... no desoldering required. That'd sure make troubleshooting easier.
Also, the expression pedal is dual-gang... considering the various unknown weird jacks we've seen (and the wiring issues that accompany them) I thought this would make things a bit easier.
