In the past bass players have used Showman, Hiwatt and Marshall amps and cabinets that were designed for guitars not basses, and they got great sounds and they didn't blow them all up. How was this possible if these amps and cabinets were designed for guitars and not basses? Which is more important, or should I say which is more fragile, the amp or the speakers. And how do you know if they will work as a bass rig? And lastly what makes a bass amp a bass amp and what makes a guitar amp a guitar amp?
