Need help with mixing bass with high gain guitars?

[asetic]

So this is what I have so far:

but I'm having a lot of trouble of tightening up the low end, especially on the bass side of things. For any experienced engineers out there, could I get a point in the right direction?

Thanks

on my headphones the bass is really quiet. Probably turn it up a bit, and if you get some compression in there and filter out any frequencies that stick out too much you should be sweet I realize that's not super specific but im at work in a call center so don't have all my gear to give it a good listen only my ATH-m50 headphones.
