we had a 'tech-day' a few weeks ago, trying to find something to beat the SM57, but to our dismay we couldn't seem to find anything that worked better (for this particular snare anyway)
I hope to keep experimenting, but we were really suprised that many of the higher-priced mics just didn't really sound any better than the SM57. We tried Sennheisers, Neumanns, AKGs, ATs- but the cheapo still stood out as the tastiest.
Next we've got to do a tom mic shootout.
(for bass, we settled on the Shure Beta 52 over the AKG D112)
The 57 is the "right" mic for snare. The Audix i5 is great too. Would everyone please stop using the AKG D112 for kick! It is an obsolete mic. Compared to a Shure 91 or an Audix D6, you might as well just use a radio shack vocal mic if you're going to use a D112. Sorry, pet peeve.
