I'm lost with the pre-wired pots. I made a sketch of what they supplied, can anybody tell me how to connect the mini-humbucker and peizo?
I understand two options are available,
1, use wiring supplied then out to an acoustic pedal. If somebody can fill in the gaps on my drawing to do this I'd be grateful.
2, find a SMALL acoustic pre-amp and fit on-board. Preferred option but without one at hand no point asking about wiring.
