Having some volume issues here....as in I don't have enough. Yes our "stage" volume is too high often, but it's not unreasonable. Yes, we have two guitarists, but they don't get terribly out of hand. I feel like I should be able to bury them with my set up if need be, but it's just not there. +Running a mint condition Yamaha PB1 preamp (Fender tone stock, kept at approx B: 2 M: 10, T:1) + Into a Crown XLS 2002 in Y input mode. + Into a GK Neo 2x12 ("rated" at 600w @8,) and a GK Neo 1x12 ("rated" at 300w @8.) Each channel controls it's own cab, so I can choose to back off the 112 if need be. +Amp puts out 375W at 8ohm per channel. Anything past 3 on the preamp's volume has the power amp flashing the red clip and thermal lights at me, and the cabs don't seem to be breaking a sweat, yet I BARELY have enough volume to keep up. Regardless of the slight power differences, I feel like should have enough wattage/speaker area with this setup to bury everybody if needed. I'm kinda at a loss. Thoughts?
