I was given a stereo drum track recently for a song to mix. Decided to make the best of it and see how far I could take it. Kick was boomy so cloned the track and put a multiband on each (any will work - I used LP-64 Multiband). Then set a good crossover point for the thump of your kick, maybe around 150 ish. Now solo band 1 on the first track and mute band 1 on the second track. Now you have complete control. Not sure if this was what you were already doing as you didn't say (or I missed it), but just incase, there it is!
Then a gate on the kick was necessary to tighten it up on this sample. I also automated the release time to get more resonance in the verse, and a tighter sound on the chorus. Smashed it through the Tube Leveller too for a bit of smack then used the Antress Modern Pultec emulator eq to dial in some tighter low end kick. I don't know what that thing is doing but there is something in the low end that it does that I can't get any other compressor to do. I'm sure the real thing or decent UAD plugs are even better, but for FREE, the Antress is GREAT and I can't get that sound with anything else. I'd almost consider cutting the lows with a normal eq then boosting them back up again with the Pultec emulator just to get the sound it's that good!
Snare crack I could bring out a bit with the Transient Shaper. But be careful as too much will eat into the middle of your cymbals. To counteract that, but still add the punch, you might like to add a second parallel compressed track with NO shaper on it to fill in the breaks with more cymbal so that the transient shaper doesn't eat them all away. Combine to taste. You may get more snap this way, with a thicker sound 'inside' the drums. I might just try this myself on the track. Also a bit of ringing on the snare I didn't like, so a sweep with a high Q eq found it around 500 and then I cut that out to tighten the snare a bit more.
Anyway, that was my experience with doing my first mix of just a simple stereo drum track. Maybe there will be some ideas for you there, maybe not. But I hope you get something from it, Beep!
If you want to give that Antress Modern Pultec emulator (AKA Modern Black Dragon - half way down the page) a go -
