    do piezos pickup the vibration of the bass or that of the strings??

    if it pickups the bass', could i just put them under the pickguard and get the same sound??
     
  2. The downward pressure of the strings.

    Piezo pickups need to be squeezed, and to have the pressure they are squeezed at change. So typically they are placed under the bridge saddles, where the vibration of the strings is transmitted through them into the bridge. You don't get anything out of a piezo by shaking it, which is all that attaching it on the body somewhere would do. Unless you put it in another stressed area like the neck joint, but I think that would be hard to do without crunching them (I don't think they like to be squeezed that much! :) ). Not to mention, wires coming out of your neck joint would be funny.

    I'm not too familiar with URB pickups. How do they normally attach to an upright? Unless they go between the strings and the bridge, then they aren't piezos, they are some sort of microphone. Well, I could be wrong. And it doesn't matter, I guess, if they sound OK under the pickguard?

    I remember reading that Michael Manring keeps some little Piezos around while recording. He metioned putting them on the headstock, different spots on the body, etc. The Piezo pickups I've built seem to work anywhere, as long as they are in contact with something and are under some pressure (taping them down works).
