Hey, I have a Fender Rumble 100 1x15" bass amp combo. One of the pots got snapped off by some careless ass at my church (end mini rant), anyway my local guitar shop won't touch it to repair it, and the other one wants to charge me £50. My soldering skill is fairly good and I'm sure I can track down the right pot and matching knob (I never did find it), but I cannot for the life of me work out how to get the amp out of the box to replace it.

So really... anyone had experience with these amps and know how i can get inside?
