I think it is important to be fore-warned on this . . .
The v93 and the mxl2003 are the same mic.
The v93 is not a flat or neutral mic. I used to own one, and frankly, I found it rather bright.
Very much so, actually. When used on several tracks, it had a way of making my mixes sound somewhat harsh; overly-bright.
I would look at it as a color mic. If you're not getting enough beater click out of your kick drum mic, for instance . . . or if you have a track like accoustic guitar that just really needs the extra high end boost to stick out in a mix; or maybe your voice is really dark or you don't annunciate well. This mic might be ideal in these situations.
It's very bright, but not nearly as harsh as it's brother, the mxl 2001 or something like an NT1, so don't think I'm totally dogging the mic or anything.
Honestly, though, if you're looking for an all-purpose mic for layering several tracks with, I would honestly look elsewhere. The Studio Projects B1 would make for a much better candidate due to it's (comparitively) neutral character and flatter response.
