Michael has been modding mics for about a decade now. The stuff that he puts out rivals mics 10x more expensive, as our friends at the Deli Magazine show us in this video.

Any one of these mics is good enough to cut an album with. There will be differences in sound, but as you can hear in this video, the performance, the engineer, and the room have a much bigger impact on the final results than do the gear.
