I played a couple of private party gigs this weekend in some less-than-ideal rooms without PA support. The first was a club in an older building with linoleum floors and tall ceilings but filled with people, the second in a former rail station ticket area: long hall, super tall ceilings, few people. In both situations I was pushing my Ampeg B2r with a 1x15 cabinet (4ohm neo speaker). In the first gig I had to crank and was a bit distorted/farty but very much in the musical mix. The second gig I had to crank gain and volume to about 8 to be heard but still was low in the mix. Oddly enough, the guitar next to me had to keep his amp on 2 to keep from getting crazy loud. This makes me think it was all in the room acoustics. Question is, would more power help? Or a different cabinet? The B2r is rated 350 watts at 4ohms. I've been planning on buying a new Portaflex350 to replace because I like the tone of that series and the weight of that model and often seem fine with 350 watts; but would going up to the PF500 help with my room/mix issues? I've read people say there's not much perceptible volume difference between a 350w and a 500w amp, just more headroom. Does that mean I'd have a "cleaner" sound with more wattage but just as easily get acoustically lost?
