anyone have a 700RB? I just got one and it sounds beautiful, and seems much louder and more efficient than the SWR bass 350 that I used to have (also a great amp though). But I hear that some of their stuff is unreliable. Anyone have any problems with this particular amp. If so I may try to sell it while I can, because I need it to last through years of gigs & road travel. I'd like to keep it though - it's a hell of an amp.
