I just finished a gig at a 400 seat theater using my Germino 45 combo. I was using a Keeley compressor for a little boost and a MAD distortion box. My amp volumes ( I jump the channels) were around "4". That seemed really loud to me but anything less just doesn't "cut". My style is blues. What volume do other players use and please include your style as I would expect shredders to have everything dimed.
