The Best Brass Warm-Up Jr Trombone practice mute is a plastic version of their wonderful metal practice mute. A bit quieter than the original, it's excellent warm-up and practice mute. It allows playing throughout all ranges and dynamic levels with uncompromising intonation and tone. You can play almost anytime, anywhere without projecting a resonant sound, allowing for backstage warm-up or apartment room practice. These mutes are very small, barely protruding from the bell. You can store it right in the bell inside your case.

Made in Japan.
