I feel that AMPEG has tarnished the name SVT by nameing everything that make a SVT.For crying out loud thay have stomp boxes they call SVT! Thats like Chevy labeling every car they make a Corvette. "New for 2007 the all new Chevrolet Corvette HLF-3 Pro " I've mentioned this before but it really ticks me off to no end. I love Ampeg,I wouldn't play anything else and I like their other amps,I have a 3 pro. But let them stand on their own merits.B15n,V4B didn't need to be called a SVT to be sucessfull.
