Yamaha's next generation SILENT Brass delivers greater playing enjoyment, anytime, anywhere. The new 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. Lightweight and Compact - Pickup Mute Significantly smaller and lighter than previous versions, the mute offers superior muting performance, delivers excellent intonation in all ranges, and natural playability. Powered by Brass Resonance Modeling Yamaha's original digital technology produces a truer tone without a mute by adding the characteristics of the acoustic environment through which the sound travels from the horn to the players ears. Suggestion - More Enjoyment With The New SILENT Brass Connect the Personal Studio with an audio player or a smartphone to enjoy playing along with your favorite music.
