I went and tried out some combos at GC today. I played through a SWR Workingman's 15, GK700RB?, an Ampeg B2, Ampeg B100-R, and an Ampeg BA115. The Ampeg B100-R and BA115 blew the other combos away IMO. The other 3 sounded good but didn't have near the warmth of of the B100-R and BA115. I wish I could try one of these amps at my church so I would know if it is powerful enough. By the way one of the best sounds I've heard from a bass was a Stingray 5 through the B100-R. It was awesome!!
