I'd bet money that they use different pre- and post- filters, too.
It's very instructive to play with this setup of effects pedals:

 graphic EQ -> distortion -> graphic EQ

For instance, giving a heavy pre-boost to the lows / low mids
will make the sound "fuzzier" but soften the attack.
Think 1970s metal... sabbath, dude!
The resulting mud can be somewhat reduced by lowering the
bass on the "post" EQ.

Conversely, cutting the pre bass, and boosting the post bass,
will result in a sound that still has a lot of low end
but has a much sharper attack.
