BTW, though just announced "officially," it looks as though it's been on the market for a few months already. If any of you out there has one, and wants to share your experience–good or bad–please add to "Comments" below. Thanks.
Gearwire: "MudGuard is a new microphone isolator designed to help isolate monitors, amps, microphones, and stands in recording studios from hard surfaces...Ideal for voiceovers and vocals, the Auralex MudGuard features the company’s Studiofoam sound-absorbing acoustical foam, which helps to reduce excessive room ambience and off-axis sound. The MudGuard mounts easily to most microphone stands and clips and has an adjustable height."
