Yeah mate, send me a PM, or take a look at Corksniffer's Build thread:
https://www.buildyourownguitar.com.a...orksniffer%27s
the diagram is shown in post #17 on page 2.
the circuit i am using is shown here post #61, page 7

The key difference is Corksniffer's is finished and working, without pre-amp. Mine is still in the works, and the circuit is as yet untested.
(I get distracted....a LOT and often!), I have only just put sanding sealer on the body, and have yet to manufacture a new face plate for my frankenhacked Fishman pre amp.
