You know I've always been a fan of your kicks Krim. And try as I might, I just can't get them as good as you do. But CC just tipped me off to using saturation on TomCat, and what a world of difference that makes! Tons better than comp's and maximers/limiters and all that.
As a rule though I usually only comp kick and snare. I certainly comp the bass as well, but as a rule I never sidechain it. Then again, I usually prefer the Brian Wilson poppy pick basses. So I try to get the bassline to play as natural as possible to the drums with velocity. IE; da-DA-da-DA, dee-DEE-dee-DEE. Only if it's a real heavy reggae or synth bass will I sideshain it to the BD.
