hello guys! can anybody of the double-dassists help me out by comparing these combos: gallien-krueger mb150s112 (or whatever it is really called) the new g-k backline 10 and/or 12 swr workingman's 10 and anything similar i may have left out? as you can see portability is importanat to me, still i don't want to compromise my tone too much. by the way, i'm using the realist through a sadowsky outboard. thanks a lot.
