Hello.
Sorry about my English.
I'm from Brazil.
My name is Alcides Cursino and I 'm making a piezo bridge for CBG . I wonder if I should put 1 or 2 piezos in bridge for better sound .

Did you get this sorted out?
From my (limited) experience, 2 disk piezos wired together in parallel produce less hum than just one. But they all hum just a little.
As for the problem, try running a wire wrapped around the screw to the ground lug on the output jack.
Try a piece of aluminum, brass bolt/screw or bone. Are your strings grounded?
how can I do this with piezo ?
Repost and see if it goes through.
have a problem: Embed a piezo a wooden base and put a screw top to make a bridge . When I called the amplifier , he began to make a noise ; As a noise or something. When I took the wooden base of the screw the noise stopped . Does probema is in the bolt material ?
not 100% sure what you are asking,but firstly,is the screw making contact with metal rim AND ceramic of piezo,making a short circuit? sounds like you may have an extreme feedback problem,try encasing the piezo element in some type of isolating/deadening material,hot glue/leather/liquid rubber etc and see if that helps
The piezo was stuck beneath the wooden base with hot glue and isolated with the same glue. The screw was placed at the opposite end of the wooden base and introduced noise . When I removed the screw the noise stopped.
I assuming that the noise associated with the bolt material which must be of a ferrous metal .I realized, in research, who all bridges piezos have seen, are made from bone or brass.
For some reason your post isn't coming through.
So I guess you now have 2 problems. Hahaha
