Wiring help for 9v Pre-Amp

[WeirdBits]

You're planning on embedding this in the guitar to use with a piezo pickup, right, rather than trying to use it to amplify a standard magnetic pup? If it is the latter then it probably won't work well due to the low impedance of magnetic pups vs the high impedance of piezos.

Thanks for the info Scott.

Yes I was planning to embed the pre-amp and not use any of the controls on the unit, and just have an external volume pot. I was undecided as to what pickups to use, but it appears that magnetics are out of the question. So if I want to use this pre-amp it will have to be with a piezo. Hmmm.

I need to rethink a few things now. If I did use this pre-amp with the piezo do you think that a second volume pot would work OK?

And one more question, there are 3 wires going from the pre-amp unit to the output jack. What do you reckon, stereo or something else going on?

Cheers mate
