I might get ripped a new one for saying this, but sometimes you don't necessarily WANT to cut through when you're playing in a heavy band. I know with my last band (Metal/hardcore, a la Haste The Day) I kicked in my EH Big Muff to basically copy the rhythm guitarist's tone. Granted, people in the audience probably couldn't make out my individual notes vs. the guitarists, but it made a HUGE wall of sound.
