Hard-Rock Mix - Real Everything, No Samples - Critiques please

Hey guys, would love to hear some critiques on this mix that I'm near completing.

Used a Tama Starclassic; the band wanted a natural sound so I went without samples. Lucky the drummer was a solid hitter.

Tracked guitars through my Ceriatone 2204. Mic'd with a 57.

Tracked bass through the bassist's rig, Sansamp RBI or RPM (cant remember now) & a Crown poweramp into a GK 4x10. Mic'd with a D6 close on the grill.

Let me know what you think I can improve!
 
I think the bass could fill up some more space. I don't think it's so much the low lowend of the bass. There just seems to be something missing between the low end of the bass and the guitars. I like the drum sound overall.

Edit:after second listen, it's the guitars missing something not the bass.
