I'm going to order a headless David King 6 string in a few months. I was just browsing the Klein electric guitars page and read that Bill Frisell has a piezo in his guitar with a separate output. I've thought about piezo's in my bass. My question is, would it be possible to send the piezo's to a preamp that is then put into the effects loop of my Glockenklang Soul amp? Then I could eq the piezo's separately from the magnetic pickups and then mix them. It would also allow any affects that I use to be separate from the piezo if I wish, such as an overdrive.
