I'm thinking about getting a new amp to lessen the load I've gotta carry into gigs. Right now I'm rolling with an SWR SM-400 w/Goliath 4x10 and Peavey Firebass 700 II w/matching peavey Tour 4x10 (heavy as hell). These rigs are great but pretty goddam heavy and I keep seeing more and more compact, ss amp heads the size of external hard drives. Are these worth checking out or should I just keep saving my pennies for an Ampeg V4B with the 212 cab? Even that rig would be much lighter and would sound amazing.
