I had to ask because of my concern but I play an SVT II Pro through an 8x10 cab in a metal band and I have tried a couple different settings and nothing seems to really cut through the mix of my loud ass guitarists and a thunderous drummer until I cranked the "Master" to 10 and set the "Gain" knob to about the 9 o'clock position. This setting is monstrous as hell and the bandmates really dig it but does this screw the tubes up? I just want to know because I am a noob when it comes to tube amps since I just got this amp a little while ago...Thanks-Andrew
