Yamaha Silent Brass Euphonium Mute System

You want to play when and as you like, without being confined to 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 Yamahas 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.

Features

Easy to attach and remove - The mutes are designed to attach and remove smoothly and easily.
Fits neatly inside the bell - A new compact design now lets you put your instrument in its case with the mute in the bell.
So light you'll forget it's in your horn - These mutes offer better instrument balance when in the bell and greatly reduce stress when playing.
Specially designed mini microphone - The microphone performance, it's mounting position, and the surrounding mute design were all optimized to bring out the full potential of Brass Resonance Modeling
Brass Resonance Modeling™ Ver.2.0 - Brass Resonance Modeling™ is original Yamaha technology that effectively cancels the characteristic closed sound of a mute, reproducing the open, natural sound of the unmuted instrument. This reduces stress on players by allowing them to practice and play freely without feeling restricted by the mute.
