What kind of amp do you use and how many watts is it? Do you play in a band/if so what style of music? I am trying to get some opinions. Basically I have a SWR stack. The 350 head with a Goliath III 4x10 and a Son of Bertha 1x15 on the bottom. Running both at 4 ohms to get the full 350w. My main style of playing is in a fusion electric/acoustic band. Not much volume needed so I assume this head is plenty. I also do session work with "metal" bands to alternative rock. I just practiced with this new band I'm doing live session work for and they play very loud. The guitarist has a mesa boogie 2:90 pwr amp, damn loud. I didn't bring my rig but instead used their EX bassist rig, which is still at their practice space (he has an Ampeg rig with 8x10 tower!) in your guys opinion do u think I will be able to compete with these guys with my SWR rig??? Or do I need to return my 350 and get the 750 and suck up the extra $500. I'd rather not because I'm broke as is but I will do if I have to. What u think?
