Probably not that easily defined without a meter hooked up.... but my experience and my own ear tell me that the range is bigger and the sound is louder. I have a Fishman Solo with two inputs/channels and used that amp to test my piezo setup and there was a distinct difference.... I have not, however, tested the larger disk against two smaller disks wired parallel or serially to the jacks.
David, I think there is a difference with the larger disks so I use those almost exclusively on instruments that get piezos. I did a side-by-side comparison with both sizes installed into the same instrument with dedicated jacks to each one and there was clearly a bigger sound with the larger disk. I think they can be a little more difficult to tame, though, so it's best to experiment with placement and dampening techniques before committing to closing the box and stringing it up.... hope this helps!

Bigger sound, as in more volume, more range, or is it easily defined?
Thanks, BeatleJuice and David!

Great ad and photo!
The figuring on that neck looks really nice. Have you found any difference between 20 and 27mm piezos? Or have you tried 20's at all?
