Double Bass Affixing piezos with minimal damage...

[ZombieGhosTrain]

I've got a pickup with two piezo discs on it, and I found I want one on the top of the body, near the F-hole, and one on the bridge. What are some good ways I can keep these here? They aren't self adhesives, tape doesn't seem able to exert the amount of pressure I need to have placed on it.

I need a way to semi-permanently attach these, so I can take them off without doing damage to the finish or anything. The bridge and back of the ebony fingerboard I'm not so worried about, but the top of the body... any suggestions? Thanks.

A couple of the 3/4" per piezo.
epoxy one to the pick up, the other goes on the other side of the bridge or inside the bass.

For the bridge pick up some friction disks

For the bass body glue on some thin rubber like a cut up mouse pad.
