I had a Peavey amp that was decorated with stickers from various concerts I attended in the late 70's, early 80's. I loaned it to a friend and never got it back.
Terrible sounding amp, but the stickers gave it sentimental mojo. Wish I still had it.
It seemed like in the '80s just about every garage band around here had those Peavey 2x12 combo amps. I could never get a good sound out of them, but then when I'd play somebody else's, I'd be plugged straight into it. I noticed most guys that sounded decent with 'em had alot of pedals.
