Thank you for viewing. Introducing the okura+mute practice mute for tenor trombone. As you can see in the photo, the color is red. This high-performance practice mute was conceived and developed by Toshio Okuda, a trumpet player. Above all, its compactness is unparalleled. It fits snugly inside the bell, making it ideal for warming up in hotel rooms during trips. It has only been used a few times, so there is no wear on the cushion. Many ideas are incorporated from the user's perspective, such as being able to disassemble and wash it to maintain cleanliness, and having two different types of air holes. It effectively silences the sound and is an excellent practice mute that makes you want to keep playing. *The trombone used in the fitting photos is a Courtois tenor bass. *It will be carefully packed and shipped. *Returns are not accepted to prevent product replacement. *We are sorry, but we cannot offer a discount.
