Back in high school, I was playing in a buddy's basement through a stack that had, among other things, a Peavey Super Festival F-800 going into 2 18" folded cabinets. Oddly enough, the kitchen was right above us. 3rd song in, mom comes running downstairs in a huff saying that I had rattled a bunch of plates out of the kitchen cabinets and knocked 2 pictures off of the wall in the den....
I think I was playing the whole house!
