Hi there, does anybody know this Amp? Found it in a friends Basement, since i only have a peavy Microbass , I would like to play the Randall. But now it is broken and i want to have it fixed. But is it worth the trouble (and the money)? Since Im here in Germany and Randall Amps aint that popular around here, especially the bass amps, theres nobody who can tell anything about that one. So does anybody know about the Randall rb 90-A. When was it build, what was the official sellprice, is it any good or will i have to recycle it?
