I like hitting an amp like Marshall, Orange, Matamp etc with a fuzz pedal.
more poweramp than preampdist from the amp.
lotsa room on drums.
do even less soloing (I mean putting instrument in "solo") while mixing than usual...
actually...try to not do that at all, the goal is not the cleanest sound but one big sound....I'll usually have everything playing at the same time and then keep jumping back and forth between intruments during the mix.
otherwise you might run into problems with your bass freqs (you don't want it boomy or muddy but still big).
but these are just standard tips of course, nothing new or groundbreaking,....sorry, I just don't have any time atm to help more
