Hi, I just bought a Blues Deluxe Reissue and I am very pleased with it. The thing is, it fell on one side in my trunck when I was going to a show. The sound was loud. Nothing seems broken in there and the sound is still the same. But there is something rolling when I tilt the amp from side to side. Sounds like a screw or something but I cannot see it. I checked for at least half an hour. It's just really bugging me. You guys have any idea where it could be??? i did open the back panel and the circuit board and everything seems intact. Could be in the speaker or something?? I would also like to know if different tubes can make my clean channel break less early. It breaks up at around 3 or 4, which is the volume we jam at. It doesn't really matter for gigs because I am miced but to jam it kind of sucks. Anything possible? Thanks!
