Everybody!! ....."Hello Emkay!@!!"........anyways here's my 2 cents after many years in the "session wars". This is the recipe that I have found works, and it's really not much of a secret--
-a snare drum that is true (round)
-bearing edges where the heads "sit" should also be "true"and cut in the case of wood, or "pressed" in the case of metal at the proper angle
-the snare bed, the part of the bottom (batter side0 of the shell where the "snares" span, should be the optimal angle and width depending on the number of "strands" of the snares
-make sure the cord or nylon strips that support the snares are properly seated, tensioned and connected to both the "butt" and the "throw off"
-in my experience, I have found that coated ambassadors on top and clear diplomats on the bottom (Remo) seem to be the magic combo heads, but don't last as long as the "thicker" heads, but they don't "choke" the drum as much as thicker heads do, ofcourse proper tuning of both heads is also very important
-in my experience, I have been surprised how much "bigger", smaller drums sound in the studio
-if a drum gets a little "out of control", just a "rolled up" piece of gaffers, or "moon gel", or the old wallet trick works, if you like the more "dry" snare sound
-whether the shell is wood, metal, composite or whatever, most of the above holds true
-with a "good" drum played by a "good" drummer in a "good" room, the rest is easy----add mics ,pres etc. to taste!
-this all might be alot for a non drummer, so here is what I suggest. Most drum shops are pretty friendly places. I'm sure if you went with your snare or snares and voiced your concerns, they should be able to check to first of all make sure the drums are physically "correct' for recording. If not, they will tell you how much it will cost, if they're worth the expense to make the drum(s) recording ready. If the drum(s) are fine, then just new heads are in order. Let them put the heads on for you, watch and ask questions, that'll help alot! If your drum sucks, let them recommend one good workhorse snare for you that fits your budget. Make sure you go to a shop that's not part of a franchise like Guitar Center etc., you'll get better more friendly service at a drum specialty shop.....good luck....hope this helps....I'm sure other drummers here at GS will gladly share their secrets, advice and insight......peace,,
