I bought this amp yesterday at a pawn shop. I even tested it out, it played nicely for a while, and I took it.

I played it again today, and it started buzzing really badly after 5-10 minutes. Tried turning it off, unplugging it, letting it sit for a while.. The amount of buzzing goes up with the volume too, so I cant just play over it. Buzzing stops completely when I remove my cable.

I know for a fact that both my cables and guitars don't buzz.

Anyone know what's going on? D: I don't want to return it

Ah, forget it. There's no why this can be a cheap fix, if a possible one. I'm returning it later
