  • David, yeah it works! But could be better. I didn't get the same piezo as everyone else has, but it definitely works. Needs a preamp -- which is what I understand about all piezos. At my first opp, I'm ordering http://store.qkits.com/moreinfo.cfm/QK17 . Plus you can find more here -- is you haven't already found them.

    I mounted mine speaker-side down right under the bridge as to get the sound and the vibration. I might even add another. I have seen a schematic somewhere which has two piezos in serial. Can't seem to find it now.

    Thanks for the reply! Good luck.
  • Hey Wes,
    So have you wired this puppy up to see if it works?
    So that is the little speaker built into greeting cards... right? Is this proven technology or another leap outside the box?
    Please report the results.
    Thanks... cool pics.
  • It's alive. It's... ALIVE!

    Works.
