Ok, here is one for the "techie" type people. Maybe even Bob Lee himself could clear this one up for me. I have 3 volume knobs on my amp (pre/power set up, gain, preamp volume, power amp volume). I was wondering, what kind of setting(s) would give me the best signal to noise ratio? Would I maybe, set gain to max. without clipping, turn power amp volume all the way and control the overall voume with the preamp volume knob? What would be the best way?
