Yamaha SB5J Silent Brass outfit for Tenor and Bass Trombone

You want to play when and as you like, without being confined to a time or place... Yamaha’s next generation SILENT Brass™ makes it happen. The SILENT Brass™ consists of a smaller, lighter, freer 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.
