Hey, Andrew, thanks for responding. It had been unplugged for a while, so I just tried hooking it back up to those channels, and they're still not doing anything.

Mojo, semi. It's shag-type as area rugs.

It did feel like static discharge when I touched the top of the case. So is it ever extreme enough to do damage beyond pushing the amp into protection?
