I'm scanning your online catalog and seeing 20mm/27mm and 41mm piezo sizes.  What are

the differences..are there any differences tonewise?

 

Also..you show a 250K pot and a 500K pot.   I have used a piezo tune-o-matic bridge on my homemade

Les Paul types and the volume control supplied by LR Baggs is 5 meg ohm. Piezos are high impedance

devices according to my understanding and tube amps have typically 1 megohm input impedance.

 

Now a 500k for a humbucker pickup or 250k for a SC (single coil) sounds right, but I would think

that if the piezos are wired directly into a volume control, it should be around 1megohm at least.

Am I correct in this assumption?

 

What about wiring the two piezo's in parallel. Someone stated that two piezos will sound louder than

1 piezo or two wired in series. Again this appears to be the result of the transducer's very high

input impedance.

Thanks for the quasi-scientific explanation on piezos.   I already wired mine up in parallel and even included

a tone cap/pot..although the tone pot is for the SC more than the piezos, even if they are switched

through the 3 way.

Basically, they sound ok with 250k volume control..which I decided to use because of the SC and the fact

that Fender uses 250K vol pots on their SC, although Gibson (I believe) uses 500k pots on their P-90 SC.

I agree that the piezos lack bottom end and are basically "fair to middlin" as far as frequency response.
