SM7's are/can regularly be used on snare and kick, when they aren't doing vocal duty.
And since it was brought up the AEA TRP rocks my world with my shiny box ribbon, ok maybe a overstatement but it seems like a good buy, I think we paid $699 for it from fullcompass. Oh, and I have used it with a SM57 on vocals, very FULL and clean gain. Not as colored as my VTB-1s, I know some may call the VTB-1s something other then colored, but its the best I can do. Just be warned if you missed it the AEA TRP does not have phantom power, so its good for ribbon mics, tube mics that have their own power supply that don't need phantom, and dynamic mics. And no DI either, just clean, FULL, nice gain.
