Has anyone used a single Bag End 15 in a gig? If so, what kind of amp did you use? I've been trying to figure out the best way to go without carrying a lot of weight. I've used combos for awhile (Ampeg B100R) but 65 pounds at the end of the evening gets kind of heavy. I also have the Workingman's 10 and coupled it with the Bag End 15 but it wasn't enough power to be heard above the drummer.
