I am trying to figure out what Amp and Cab combo to get. I want/need a clean (no distortion) system that retains that clean tone throughout the volume level. Everything I have tried has been clean until the volume starts to increase, then....distortion sets in. Suggestions? Have a Peavey Combo 300 now, and is ok up to a point. But, it just starts to distort to early for my liking. Tried a GK 250 but it was just too muddy (FOR ME). Thanks.
