Do not be ashamed of using a pedal in front of your amp. I use the modded Boss OD-1 in front of my Mark I. With a 12AT7 in V1, I am able to get some f'n EVIL tones. By lowering the gain in V1, I can set the level wide open on the pedal and set the drive to taste. My amp has the effects loop mod like the Mk IIB with the "post FX level" knob on the rear. It acts like the output level knob on the MkIV. This setup has dropped many of "gain freaks" to the floor. And when I want a blues sound, I switch off the pedal and the gain boost with the under chassis footswitch, crank the preamp volumes up, and work the volume pot on my guitar. It gets a great vintage blues sound this way with my 'Paul (Think early ZZ Top).
