Hey Rob, thanks, but I tried all that- with the mechanical gain turned down, I get virtually nothing out of it at all, from any module. I've had the PCY for years, and used it with my original TD-10, a MegaDrum and now the eDrumin. It's just never played right. Could be that my specific example is just plan broken!
With three piezos, it plays great now, and I'm really enjoying the eDrumin too.
