I was playing at the same volume and settings as I always have. I tried a different guitar and it was normal, so it is definitely the guitar and not the amp. The cable and metal parts on the guitar also seem really microphonic (tapping on them comes out very clearly from the amp, even when not on the distortion channel).
A week or so ago my cat kinda knocked the guitar off of its stand. It didn't sustain any obvious damage, but now I'm wondering if that caused this to happen. Does anyone have any suggestions? I could open it up and have a look but I don't know what I'd be looking for.

Unfortunately it doesn't look like it's a loose plate in the pickups - those both look secure and didn't see anything that looked weird in there. I also took out the electronics to check those out and don't see anything out of the ordinary.
If it is doing it on either pickup selector position, does that decrease the likelihood that it is the pickups themselves?

It looks like mine don't even have "covers", they look like they're constructed of just a solid piece of plastic which has magnets glued or otherwise affixed inside. I've never taken apart a pickup before but it doesn't look like there is an easy way of taking separating the plastic part from the other parts. Do you just pry them out? I'm worried about damaging them.

A few other things I've noticed:
- When I flip the middle switch (I think this is phase reversal?) I get a very loud buzzing in addition to the feedback, as though the guitar is not grounded at all. I've looked at the electronics and there do not appear to be any loose joints or anything. Is it possible a pot or switch has been damaged?
- The ground plate inside that cavity is loose. If I pull it out there looks like glue or wax that used to hold it in place. I have got out all the old pieces with no change to the sound. I am not sure the best way to fix this back in place - it's hard to tell what it was that was holding it down, but it looks like some kind of dark colored glue. I'm not sure if this would account for the problem or not. I kinda temporarily taped it down just to keep it from floating around totally freely in there with no effect on the sound.
