Temple Audio Design Replacement Adhesive Small

Once you've cleaned of a used pedal plate, this is really the best way of getting pedals to stick again. I've tried other adhesive tape, and pedals just fall off, but not with this.

My only complaint is that is a bit expensive for what it actually is, like way more expensive than it should be.

You do need to get 95% of the old goo off the plate though, and so far the best way I've found is to use a heat gun on a mental "burn your hair, eyes and hands" setting, but once you've got it off (some residue is ok) and stick one of these back on, you have a good plate to mount another pedal with.

If you're into the temple audio system, these are what you need to reuse plates.
