a bit dissapointing

so i hit glued my piezo to the lid of my box, pluged it in and... nothing. i had done the tap check before i glued it and i could hear it thru my amp. what could have happened? i tried to get the piezo off without damaging it but that didnt work so i had to snip the wires. could the hot glue have damaged the piezo crystal? should i try putting it between to pieces of felt or just tapeing it?

I've been using 3m silicone exclusively on mine, it seems to work very well; not only secures the piezo but eliminates the "microphonic" tendencies to a large exent. ( The tendency to pick up every little contact noise with the body of the guitar)

The first couple I sort of "buried" in silicone, but now I just put a heavy layer on the back of the piezo and press in place.

I have used this method on both of my resonators, gluing the thing directly to the underside of the resonator under the bridge.

I do the same with the double sided tape. I put another strip over the disc with the backing still attached. Works really well.

Agreed. But on the hot glue angle, a number of people at the forum swear by a thin layer of glue on the face of the piezo disc to cut down on feedback and squawk noises.

(Hey Matt, "squawk noises" -- another highly technical term!)

Incidentally, 3M brand double sided tape works really well for securing a piezo disc.

Thank you, thank you, thank you. I was racking my brain trying to figure a good way to place that thing.
