Experience the Evolution of SILENT Brass Pickup Mute and Personal Studio for Trumpet & Cornet (with Brass Resonance Modeling )You want to play when and where you like, without being confined to a time or place Yamaha s next generation SILENT Brass makes it possible.

A new compact design now lets you put your instrument in its case with the mute in the bell.* Please note that the Pickup Mute may not fit some instruments with significantly different bell shapes or bell diameters.
