I'd say clamp it. It's not worth taking the risk of zapping your 
circuit. If you smack a bare transducer directly with a drum stick 
you could get hundreds of volts--briefly. Sort-of a loose cannon in 
the circuit there.

Anybody done any tests? Let's have a voltage peak contest... 
(breaking the transducer means instant disqualification)
