I've heard that the reason a 50W tube amp outdoes a 50W solid state is the shape of the distortion from tubes plus the harmonics and stuff is perceived as louder. They don't distort in plain ol' square waves like a solid state. Or something like that. I noticed this with my sister's 20W Cube when I was playing on the Tube Driver sound. The amp, though not really all that loud, was cutting through my backing track extremely well. So if I ran my amp (solid state) clean at max volume with a tube simulator overdrive like the Boss ST-2, in theory I would have more perceived volume because of the distortion characteristics. Does this idea hold water?
