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. David L.
