I need to build a preamp for a Fishman pickup.  This is a piezoelectric
transducer that wedges into the bridge of a musical instrument.  Can
anyone provide an electrical equivalent circuit for a piezoelectric
element?  I understand it is pretty high Z, and the output level is
similar to that of a microphone, but my first attempt at designing an
interface yielded results that were quite bass-shy.
