If you're using the Avatar library then you have some fantastic snares, toms and rooms right off the bat. Fight the urge to over-process. That's your biggest enemy.
Ok here is your golden plug-in:
Waves SSL E-channel
The in-line EQ and compressor on this thing works great on drums. Start minimalistic, don't go overboard, just tweak the EQ, do some mid cuts, and some high and low boosts to give fidelity to the drums.
-Kick and snare work great if you turn the shelf into a bell boost. You get more definition and cut from the boosts. 300 to 500hz can be your problem areas if things are a little too muddy.
-Suck 600 to 800 and 200 to 300hz on the toms, crank the highs with a shelf, and bell boost the lows at like 70hz. Fast attack on the compressor, ratio maybe 3 or 4. Take off around 3 to 6dB, to taste. Instant fatness.
-Hit the overheads with fast attack compression, 4:1 ratio, but VERY LIGHTLY. I'm talking barely any movement at all. Just something to add a bit of excitement.
-With all of these settings, always have the compressor release at its fastest (100ms).
-Slam the living shit out of the room. Like 10 to 20dB, all buttons in on an 1176 style plug-in if you have one. This will effectively turn the room mics into reverb ambiance. Just a wash of awesomeness to fill out the back and add air. Use the mid and far field room mics too. Throw the snare into them - no need for anything else.
-Consider cutting the cymbals and hats from the room mics a fair bit. Also consider cutting the hats from OHs if you need. EQ to taste. Then slowly bring it up into the back of your drum mix. It will unify everything and virtually negate the need for a reverb.
-Kicks sometimes like a 50 or 60hz sinewave side-chain gated to them. Just enough to fill out the subs. If I'm not mistaken, Randy is still fond of this. It's a similar thing to using Joey's harmonic enhancement suggestion.
SD2.0 is almost there for you. All you're doing is tailoring work. Getting it that little bit more punchy and clear.
