The tape works, but I'd like to keep this amp in the living room, and I have a feeling that won't work out so well if it's covered in tape and sticky residue. So, I cracked it open. Everything that holds those buttons in place is screwed on from the front. From under the face plate I guess? The circuit board with the momentary switches snaps in place and has one screw between the insane and tap button (the only two that didn't rattle btw) holding it from the front. Unscrewing the controls and removing the face plate seemed like too much hassle. Instead I wedge pieces of an old paypal cash card (a little thinner than your average gift card) underneath the clips hoping it would hold everything together tighter. It's working great so far. Now the walls are the only thing rattling. :D
