I use a 2x10 (SWR goliath jr) + a 4x10 (fender bassman) and the 210 just aint cutting it with the b string. another problem, I live in boston with no car...so Im looking to just bring down the rig. I need a small cab 2x10 or maybe 2 2x10's? that will be great lightweight and take that low b like a champ. I was looking at a bergantino 2x10 and that was looking pretty appealing to me (thanks to emjazz for the suggestion) but Im looking for other input! thanks!
