You could use something like this with a peizo - and no pickup?

Thanks for the link Brendan. I like the look of that bridge. Opens up all sorts of possibilities.
Unfortunately I have to use what I've got for this build. But maybe next time.![]()
If you have the right bridge that takes a piezo mic you could then use this Robin. But may be costly
it's a stereo socket with used to power on the system. Insert a standard mono plug and it completes the battery's negative connection by shorting the ring to the sleeve, turning the power on. You will be able to use a stereo version of our standard open guitar jacks to do the same thing, rather than having to use the endpin jack.
You could run another volume, it probably uses a 50K pot, how you connect it would depend on how the original is wired. Are you going to make the preamp's controls accessible on the back of the guitar or hidden under a cover? If possible I'd leave them accessible (along with the 2nd volume) and do a combined piezo and magnetic pickup build. If you google 'piezo preamp with magnetic pickup' and similar terms you should find a lot of layouts where people have combined their piezo circuit with a passive magnetic pup circuit etc. so you can have both in the one guitar.
Scott.
Thanks again Scott. The original plan was to max everything out on the pre-amp, "set and forget" and hide the it under a cover. I would control volume with the second volume pot and save a few presets in my fx pedal to take care of tone settings.
Thanks for your time mate, I think I need to do some more research. I think you have just saved me a massive headache.
Back to the drawing board.
Cheers

Is there a specific reason you wanted an onboard preamp to use with magnetic pickups?
If so, you can easily make your own small preamp for around $10. I'm looking at an onboard circuit now that will give 2x-10x amplification. It has 1 switch, 1 gain pot and 1 IC and you can build it on a small piece of Veroboard. Very easy to build.
Scott.
No logical reason Scott. Just had it and some PBG original magnetic pickups laying around and thought, what the heck, I might as well put them to use. I really need to keep myself busy and although I could easily spend the time doing some much needed house reno's the only thing that really works for me at present is to throw my energy into guitars.
Based on what you have already told me my thinking has changed somewhat and I might use the Piezo in another guitar. As I said, more research needed.
That DIY pre-amp sounds very tempting and although a complete novice at electrocutions, I would be eager to try this for a future build.
Ta mate
