I have the 2003A. It's a great mic if you want things to have a lot of top end detail. I call it the anti-ribbon mic. It's basically the opposite profile of all my ribbon mics. A little thin on the bottom end, fairly flat through the midrange. Slight dip in the upper mids. Big bump up in the treble frequencies.
It's a mic that I like for things where I don't want a ton of bottom end, but do want some sparkle up top (pop vocals, acoustic guitar, tambourine, shaker, triangle, wood block, male vocals that sound dull on their own, female vocals that you want to sit above everything else, etc.).
It's a mic I dislike for all the opposite things. It's too bright for electric guitar. It's too bright for high pitched vocalists. It's too thin for vocalists with a deep voice that needs to be captured as such. It's too thin for bass, unless coupled with a DI in which case it's still a little bright.
This is a minor complaint, but the included shockmount is absolute garbage. The bands continually eject themselves and you have to reassemble it. A threaded mount would have been much preferred. MXL offers this kind of mount on other mics of theirs, so the omission has always seemed strange to me.
