IMO of course!
but for me, I get such a full sound from my snare's top and overheads It gives me all the fullness and body I need. I dig a full natural, woody, sounding snare.. not choked at all.
the bottom mic gives me the extra rattle/sizzle tone defining the snare as the unique drum it is, (seperating it from my toms which are 8" 10" 12" 14"). I cut out the lows for the reason of illiminating any thud or dullness sound. my mic placement is really up and under the springs for that desired rattle...
depending on the tune I sometimes will mute the top mic in the mix during early veses or bridges/breakdowns and let the bottom mic (along with my overs) give me a nice mellow section until the chorus/etc. kicks back in. so the bottom snare mic in my configuration has multi purposes.
I have used 57's, 58's, mc012's, mk319, 4033's, small and large diaphrams alike on snr. bttm. and find all work well for my needs....
IMO Dumass has quite a selection already to do the job and with valentines day fast approaching he might want to invest that $100 into his gal to keep the peace for the remaining 364 days!
