Jo-Ral B7 Bass Trombone Cup Mute – Spun Aluminium – JRTRBB7

The Jo-Ral B7 Bass Trombone Cup Mute is a lightweight, hand-spun aluminium mute designed to play evenly across the full range of the instrument. It’s built to keep the response consistent in every register, with a focused cup-mute colour that works brilliantly for big band, cocktail jazz, and section work where you need warmth and definition without fighting the tuning.

Jo-Ral’s long-lasting cork system helps the mute sit securely in the bell and stay reliable over time, while still allowing small adjustments to get the fit just right.
