Hello, this is what i did :
I made a big 22" wood circle, i had an old A custom broken cymbal, so i just cutted the bell, i covered the wood with some rubber, and i glued the bell, and made a big hole in the center of the wood, i glued a piezo in the wood body, and other in the metal bell, and attached 1/4" jack to each piezo, i bought a 1/4" jack Splitter, and i plugged the two piezos to one trigger I/O input, i configured them in BFD2 and i got a nice dual zone ride, body and bell.
Hope that helps
(Sorry for my english)
