Designed by Shinji Hamanaga, Japan.
Shinji was engaged at Yamaha for many years where he designed and participated in the development of many projects. One in particular is the world renowned "Silent Brass". "Warm Up"for Tenor and Bass Trombone is Shinji latest invention.This new mute was introduced to me by NYC Recording Artist Jim Pugh.

"Now for the good stuff. The man who designed the silent brass mute (Shinji Hamanaga) left Yahama and is making horns, mouthpieces and a few mutes. His trombone and bass trombone practice mutes are INCREDIBLE. They are as intune as the Silent Brass and just a tiny bit louder. But they fit flush with the bell (in the case or bag) and they weigh almost nothing!! The Manhattan Jazz Orchestra section flipped over them - Eijiro Nakagawa introduced me to them and he and I have flipped over them."

Enjoy - you're not going to believe this mute
