Ok. Here's the dilema. I play a Musicman Stingray through a SWR 350 bass head with a Goliath III (4x10) and a S.O.B. (1x15). I like SWR but I can't seem to get enough warm bottom and punch. Any suggestions? Should I try a different head? Ampeg perhaps. I play hard rock heavy metal in a single guitar band. So, behind solo's I need some predominant bass rhythm. Any help or advice is appreciated.
