Yamaha Silent Brass SB7X Mute System

You want to play when and as you like, without being confined to time or place… Yamaha’s SILENT Brass™ makes it happen. The SILENT Brass™ consists of a small, free blowing Pickup Mute™, and the Personal Studio™, which features Yamaha’s exclusive Brass Resonance Modeling™. Used together, the two deliver the natural acoustic tone you hear when playing without a mute, making it feel as though you are playing mute free.
