How is it for high quality recording. I will be using the microphone for next to none live performances. It will be used to record vocals and then run it through a program to add effects (i.e., reverb). But recording is the primary function of this microphone. It will mainly be recording in what I making a studio (makeshift, no sound-dampening, no acoustical qualities, etc.) - but there is a remote possibility of recording my choir at Church during Mass.
It is excellent for home recording. Many studios have it on hand because it is such an excellent mike.
The type of mike you need for a single in studio recording and one you would need for a choir are completely different. You would need a different type, and multiple mikes to record a choir in high quality. Whereas you would need one to record a single instrument or voice.
The Shure is a cardioid dynamic mic. I belive that a more condenser type mic would work better for the purpose of recording a choir. And in any case you need multiple mics as various positions to get the best sound possible. One mic on a choir just will not do.
You might consider getting a minidisc recorder to try out recording your choir. Setting up a mobile recording studio is really hard. That way you can record on a single mic and then listen. When you want to do a more thourgh job you can buy the multiple mics, find the perfect place, figure out mic positioning and the like. Most of your time would be setting up the equipment rather than actually singing/recording. A minidisc with a nice little built in condenser mic is actually quite good for recording live bands, speaking and choirs.
