do any of you guys use an OD pedal? Or do you just run clean into the amp? I have a Mark IV, which IMO is one of the best amps ever made (I have used Bogner, ENGL, Soldano in the past, always come back to the Mark IV). But I feel like it doesnt have quite what I need for HEAVY guitars ie Killswitch, In Flames, Full Blown Chaos, etc. My Maxon OD808 is on the way, which I will use for live, but I was wondering is a bit much for recording? I quad track everything, which does make it a nice, thick crunch, but I want a little more balls and tightness.
