What's a piezo pickup?

  1. I've seen many posts on piezo pickups but I still don't know what a piezo is.
     
  2. From www.guitarelectronics.com :

    A piezo acoustic system provides a great acoustic sound from an electric guitar or bass by installing a piezo bridge and the accompanying electronics and controls.

    It's actually a bridge.

    Well it's acutally inside the bridge.

    The pickups themselves are quartz crystals that are (usually) placed underneath the string saddles in the bridge. The crystals have the property that when they are squeezed they generate a small voltage. Since the string's vibration squeezes and un-squeezes them rapidly, it creates a signal.

    They pick up all of the string's harmonics, unlike magnetic pickups, and also pick up a little more of the interaction between the strings and the body. Hence they can have a more "acoustic" sound.
