Havin' trouble mixing a HEAVY rock band. I know a bit about leaving room for frequencies, but I'm a little stumped on this one. The band has two guitars (tuned down a few steps), a bass (also tuned down), and busy drum parts. I suppose the good news is the singing is higher pitched screaming (no cookie monster vox). It seems like the guitar tones they want NEED that low end oomph to sound big. It's just messing with the bass enough to drown it out. It's taking a lot just to make the guitars happy with the kick. Any suggestions? Or is this more the fault of the arrangement? Or is that a weak excuse for me not being able to re-produce their thick live sound on tape (er hard drive)? Thanks in advance.
