That V900 is sweet looking. I have been peeking about for a while, thinking of getting a warmer mic for vocal recording. It sounds like the MXL 4000 might be a good bet. Doc, do you use that for close micing, or do you generally back off of it a bit? While I was looking up the 4000, I saw the MXL Genesis tube condenser. If it sounds as good as it looks, that would be one great sounding mic.

Sorry for the slow response, things have been busy at home for the last few weeks…
I use the 4000 for lots of different applications (mostly recording applications). While recording, it works very well at any distance from 1 foot to 50 feet. For voice, I keep if far enough away not to cause popping (about 18 inches) and even then I use a pop filter between the singer and the mic. They do a very nice job recording choirs, but honestly are so large as to be distracting to the audience. I would describe the tone as clear, warm, full. The tone is not harsh, brittle or boomy. They sound less bright than my Shure SM81s (standard recording industry small condenser microphone) bit I do not find them lacking in treble or overtone content. Compared to the MXL 2001s, the 4000s have a more honest, refined tone (less colored).
I have used the 4000s a few times for PA use and that can be a bit dicey. They are condenser microphones after all and tend to pick up even slight sounds. In PA use, they work best if your speakers are well in front of you and the area you are playing has no reflecting surfaces (walls) that can throw your sound back at you (and cause feedback). Of course, this sound like outside would be a good choice, but if you are outside the sensitivity of the microphone picks up the slightest wind noise. Again, using these mics for PA use can be quite problematic.
The MXL V900 is an interesting mic. We have used that mic to perform with a PA and it works as long as you have in-ear monitors. Again, it is a condenser and is prone to feedback. But I do not own a full set of in-ear monitors for our band, but I love the way it looks when we perform standing around it.
Both the 4000 and the V900 have pretty wide cardioid pick up patterns.
MXL is making some pretty cool mics these days. A friend of mine, who has been in the recording industry for 30+ years and has a locker full of Neumanns, Shures, AKGs, Sennheisers and much more, recommended I check out MXL mics about 10 years back. He claimed that MXL was coming out with microphones that easily rivaled some of the best sounding mics he had ever owned and used for a small fraction of the purchase price. I think he might be right.
