Thanks for the commentary everybody.... the extra ears really help out. Listening again, yes, the guitars are a bit boxy... one minor EQ change cleared that up. I was going for something 'savage' and I might have went a little too far.
Drums: They're a quick & dirty DFHS sequencing job, as I can't play drums that fast & didn't have anyone around to lay 'em down for real. Kick was a home-rolled sample.... one of many.
Bass: There actually was a bass guitar on that mix, just down a little too far, I guess. The bottom end is always the biggest pain in the ass for me, usually with there being too much.
Tuning: Thanks for the observation, Nitro! I'm a total prick when it comes to tuning. So much so, one client's girlfriend nicknamed me "the tuning Nazi." No, I'm not making this up. Tuning was done with G-Tune 2.5 software. I also used it to intonate my guitar, as it's really precise. Peterson actually liscened the G-Tune technology for thier "Strobosoft" program, which, IMHO, is more expensive & inferior. It's a "drop C" tempered tuning (2 steps down & then "drop D" tuned). The open C string is tuned about 15 cents lower than a perfect C... I find this helps with chording from the 3rd to 7th fret on those low diads.
Thanks to your suggestions, I've remixed the clip. You can get it here:
CLIP
Kick drum has been changed, it sounds more like a drum now.... I've been experimenting with various kick samples to try to see how much definition I can keep at louder mastering levels.....
Bass guitar has been brought up (unfortunatley, it has dead strings) & the guitar EQ has been shifted slightly to take out some (not all) of the boxyness....
BTW, here's a pic of the second amp... it's sitting ON TOP of the Mesa.
