Avantone Pro SSM Professional Shockmount Simple and effective! Solid metal construction It's a must in any studio, as well as live usage, to maintain an uncluttered mix by reducing the low-frequency muddiness that can build up in multiple, full-range, open mics Each SSM is constructed of heavy-duty die-cast zinc, which is not only incredibly durable but also adds mass, which contributes to vibration dampening/decoupling Sturdy construction with 4 O-RINGS per unit will securely hold most small body mics while "floating" them away from body-to-body contact
