Maybe it's a combo. I was just looking at a 5150 combo in a pawn shop today. I noticed it had 2 power tubes, and was missing the grill. $200!!! I'm gonna fire it up tomorrow. What a beast though. There's no way I'm lugging that around.
@Genius Gone Insane: Uh oh, What if he hooks up the guitar and starts playing while you're sleeping. lol if he's old enough to know how to unhook the grill...
