What I like to do is use a d112 inside, slightly off axis pointing at the beater, maybe 6-12 inches away. I put a little foam on the shell closest to the front of the mic to cut down on early reflections. You can get real close on a D112, Beta52 or RE20. You'll really get a solid snap with that mic. Then I'll use a 57 about a foot or two out from the front pointed straight in. I'll usually jury rig some kind of baffle system to keep bleed out of this one. some people make a "cannon" for this. They put a skinless kick shell of the same diameter in front of the one that's actually being played. My friend at Avatar studios uses a FET47 for this a lot, or an NS-10. YES, I know it's apeaker. Then, in the mix, to really tighten it up, I'll put a high pass on the inside mic, and a low pass on the outside mic. Usually at the same frequency, a la a crossover. Then, for the final touch, I'll sometimes slide the outside mic back a few ms. Remember, it's about a millisecond a foot. Oh, by the way, I use a transformerless 57. It's got better bass response for sure than a regular 57. About 10db quieter though, but that's never a problem for miking drums or cabs.
