I just purchased an original Marshall Blues Breaker from the early 90's. I have the BB II which I don't particularly care for. I heard good things about the original and I know John Mayer uses one (I'm going for his type of tone). The one I bought was also sent to Robert Keeley to be modded back in the 90's when he was relatively unknown. The owner claimed it sounded like an original TS 808 without the mid hump and harshness. Anyway, I just wanted some user opinions.
