umm, well if you're doing this, i advise you to get gates aswell. you should get a few compressors and keep em in a rack. basically, gate all the mics you have on the kit so that you can mix each mic as a seperate part. otherwise your snare mic will have the hi-hat coming through etc etc. DBX do some great gates. As for compressors, try the Alesis 3630. I couldn't tell you my favourite compressor cus i got about 15 and they all suit different drum sounds. some of the focusrties sound good. beringer sent me a composer to try out. there's some good results waiting to be found in that one. allthough,before you buy it, check out some of the LA Audio ones cus they have filters aswell. and make sure you try the 3630 form alesis too. Compression brings noise into the mix so make sure you have gates and good noise surpression! as long as everything sits in the mix, drum wise, you can sort compression later really. bass drums are what will drive the composer mad. I didn't have great luck with it. it's great for using on bass though. works wonders. I patched it into my neve desk and sent a bass track out to it and it did everything it was supposed to. it's a great unit. but try everything else. each compressor has a sound!
