Anyone ever do this? It seems like if I buss the bass and drums together to a subgroup I can get a tighter rhythm section sound. I'm getting about 3 dB gain reduction, so I don't think there'll be any artifacts in the bass track. Is this accepted mixing practice? If so, what types of setting do you usually use?; I've toyed with both short and medium attack/release times, all sounds pretty good to me... BTW, the song is a motownish pop/rock track.
