Overheads should be okay. I'm using CM90s myself. They aren't anything special or anything, but if you place them right, they give a good image of everything but the low tom and kick. Turn up the gain on the low tom as needed to compensate.
Replace the kick mic with an AKG D112.
Add a snare mic (and if you only have three toms, put the other tom mic in a drawer in case you ever need four)... something that's a little brighter than a tom mic would be. Maybe a Shure Unidyne III? You should be able to get a used one for about $30 on eBay.
for 600 i would get either a beta 52 or d112 for the kick, some es57's (the sm57 copies), then whatever overheads you want. I might try to find some studio projects overheads.
so i should keep the overheads and tom mics and get a kick and snare mic. maby my problem isint the mics right now my drms sound very distant i want them to be more in your face if that makes sence
I am also i nthe same boat. I plan on getting SM57 for snare, keeping the tom mics, the best mxl mics thati cna afford for overheads or studio projects, and then the akg d112 for bass.
