I have a few questions about piezo pickups with an active (9V battery) preamp. In a large body cbg, I’m thinking of installing a system with 2 piezo discs (or perhaps one under saddle piezo rod and one disc) wired in parallel to a blend pot (either m
Read more…I have wired a disc piezo and a rod piezo in parallel through a simple active (9V) endpin Jack preamp. I tested it before installing, by tapping them on the table. The disc piezo cane through strong. The rod piezo was faint. I plugged a different rod
Read more…I have read several discussions and articles about resonant frequency, many of them going pretty deep into the science/engineering of piezoelectrics. Much of it was over my head as a beginner, and I've had a hard time finding a rough rule of thumb an
Read more…I have a 3 disc transducer set that combine to one wire that then are soldered to a 1/4” jack. I have a rod piezo that connects (vis 2.5mm plug) to a 3 band active preamp (with a 9 volt battery), which then connects to a 1/4” jack. I would like to co
