So I've always used combos, and I am currently using a GKMB212. I am pretty pleased with the portability, power and tone. As far as gigs my band usually plays small to mid size bars. I am always D.I.'ed anyways. However, there is a very good chance that we will be playing at Vans Warped Tour next month and I'm not sure what the sound setup will be like. (and I would look silly up there with my little baby amp). I've been thinking about buying a rig. If so, probably at least a head paired with a 410 (or two). I'm leaning towards Ampeg. What do you think?
