record yourself! its the 2nd mantra of the DC's ten commandments.

the first being "get a teacher".

seriously, the more you hear yourself, the more you'll understand what it is about your groovin' that might be a little off. e.g. for me, it was a rushing and overly loud hihat. switched to lesser assaulting pair, and learned to ease back my right hand, while maintaining a solid backbeat. later i realized my bass was a wee bit in rushing, too. and now, its all slowly coming together.

also, any bassists you know with whom you can jam? grooving in any genre, IMHO, is all about team work, and you wont get better unless you play with peoples.
if ya like, when i finally find some free time from work, i'll record / click track a few bass lines into my trusty US122, and you could try practicing to them.
