typically, for heavy music you need the mics closer to the guitar speaker and the bass speaker than with other music........also, it's a good idea to mic your bass and record direct through the bass amps line out(if the amp has one) that way you can choose between the 2 sounds because more often than not, bass players (in heavy/rock bands) have bad tone.
for drums
if you plan to mic the whole set, don't put the mics too close, i made that mistake on my first session becasue i was trying to eliminate as much bleed as possible....basically it sounds like crap and you still have bleed.
i normally put mics about 4 inches from the drums (toms/snare) but i've put them closer and farther than that.....6 is about the farthest and that sounded really good......
and the further away your over heads are, the louder the set will be.
at least that's what it seems like to me, but jsut like with the tom/snare mics, they can be too close........just try like putting them far enough away from the cymbals that they don't get hit when the cymbals move up and down.......then go from there
i'm very ametuer, but i have been getting pretty good sounds with those distances
i want to write more, but my riends and i are going to a movie
