I've read all I can find about the crazy portability of having two 1x12 cabinets and I dig 12's. But how portable is portable? I'm asking because I'd like to know if I should sell my combo amp to finance some 112's. For example, would a Gallien-Krueger 1001RB head and two Avatar SB112 cabinets eliminate the need for a combo if I only bring one of the cabinets? Thanks for any help!
