I received a cheap pre-amp in the mail today, & it came with a rod piezo. My question is, can this be glued to the bottom of the sound board like a disk, or would I be better off making a hardwood bridge & embedding it into that? Or would it not make much difference either way?
That's exactly what I did with my ukulele set up, works well!
Wow! I'm guessing the string pressure caused the bridge & pickup piece to bend, all which sort of floats, causing the rod to push out through the bottom?
