When I was about 15 a buddy of mine sold me his Champ 12. It had a few years on it then. It was my main amp up until I was about 28 or so. Had it for 13 years...crazy. I played that thing in every band I was in; metal, rock, R and B, Blues....
Never in my tenure with that amp did I like it. I hated that amp from about the moment I got it until I unloaded it for a Line 6 Spider. It never ever sounded like anything but garbage. The second channel was god-awful on it. And unless you needed those obnoxious squealy-cleans the regular channel was worthless.
Had that amp forever...God help me...I hated every minute of it.
