I'm working on a license plate resonator guitar with two piezo pick-ups. The piezos are super glued to the back side of the plate, either side of the bridge.
This guitar also has a CB Gitty 3 pole, prewired, dual humbucker pick-up installed. I plan to use a 3-way switch to switch between the piezos, the humbucker or both. I'll have a volume knob for each pick-up and a tone knob for the humbucker only.
I would like the volume output from the piezos to be approximately the same as the humbucker volume output. So my question is: should I wire the two piezos in parallel as normal or in series for more voltage?
I can add more piezos in series for more voltage or in series-parallel for more oomph. What has been your experience?
You’ll have to run the piezos through an onboard preamp, series has more output though? FYI, the Fender powerstrat has a similar configuration,good luck
I read somewhere (maybe on this site) that the Piezo has such high impedence that is has trouble impedence matching with most amps. One way to lower this impedence is to put Piezos in parallel. I've tried this and there does seem to be less amp hum without loss of volume. Therefore, I say parallel.
