Vocal "Acoustic Booth" in excellent condition. This wrap-around sound insulator mounts to your microphone stand. It works great if you know how to add room ambience back into the mix. Otherwise, the vocal recording will sound quite dry, since it really does cut out noise from the room, including reverb.
The current version has a window: https://www.primacoustic.com/voxguard-vu/#voxguard-vu
IMHO, this version is better for sound control, since it has absorber instead of a window.
I'm also selling the Blue Microphones Shockmount shown in the photo.
