The consensus is already there: Microphone isolation shields are really helpful in mitigating bad acoustic recording environments, reducing leakage and helping track sweeter vocals. I’ve also been using the Mudguard v2 around the studio for various apps when the need presents itself—taking the room out of vocals, tracking ultra-dry in-your-face acoustic instruments and sometimes making my drum kit ambience mics a little less ambient. The Mudguard v2 uses a non-perforated plastic shell (16” x 10” x 14” WDT) lined with Auralex’s 1.25-inch Studiofoam wedge foam. It mounts to your mic stand with a steel L-bracket, which, along with the supplied fittings, will fit most mics, but not really tall ones. The mic should be positioned about 5.5 inches from the shield’s rear to ensure both a natural sound and reasonable isolation. The sides of the shell are not concave but convex, which reportedly focuses reflected sound away from the mic, not channeling sound toward the center (like most designs on the market), which can cause phase smearing and coloration.
