Jo-Ral Tenor Trombone Bubble Mute – Spun Aluminium – JRTRB31

The Jo-Ral Tenor Trombone Bubble Mute is a high-quality extending tube (“ET”) style mute designed for that classic wah-wah / jazz “buzz” with strong projection and reliable tuning. Hand-spun from lightweight aluminium, it’s built to feel free-blowing while keeping intonation steady across registers—ideal for players who want a bubble mute that responds quickly and sits well in the section or out front for solos.

A durable cork pad system helps the mute grip securely in the bell without drying out or becoming brittle over time, and a soft felt cap adds a layer of protection in day-to-day use.
