Here is an eq tip that works well with the realdrums that have a full kick sound, such as the nashville drums, should work well with most of the clean jazz drum sets and clean rock drums. it is designed to open up the drums and make them sound more full with less mud and a more clear defined high end. It will improve the snare drum as well as the hats and crash. adjust to your need.

What is needed;
a high pass filter at 20hz. this is a good idea no matter whether you use the other settings are not. You can go as high as 50 hz on the drum set if you want the bass to drive the mix.
a bell curve with a -6db cut at 500hz set Q at 2.5
a high shelf filter at 8K with a +1-+1.5 boost
use a compressor
Threshold until you get -1 to -2db volume cut; no more, re-add whatever you cut on the make up gain
set ratio to 1.5
set the attack to 2-5ms
set the release until the meter pumps in perfect time with the kick. If the release is set to high for the attack it will cause a pumping sound. the drums should sound more pristine but should not be pumping or sound crushed by the compressor in anyway. The realdrums sound good already this tip is just to take out any mud and make the high end sparkle.

This clears room for the bass guitar The low end of the drums thump and the high end really shines. Depending on the drum set used you may have to tweek the degree of the 500hz cut as well as you may need to move the hi shelf up higher or lower; you should always use the 20hz highpass filter. The 20hz highpass is also a good idea for the bass. make sure to listen to this with all of the instruments in the mix; Special note: make sure when compressing and adding the eq filters that you do not raise the volume of the drumset higher than you have it set in the mix, you are not trying to make it louder, only cleaner. The drum should be the same volume with or without these settings. If the volume is being raised just subtract it from the gain; listen with the plugins bypassed and not to insure the volume is not different. Hope this helps!
