The Wallace Bass Trombone Wah-Wah Mute helps your brass to produce the iconic "wah" tone. Manufactured from the finest aluminium then anodised for a professional finish it produces an even and in-tune tone across all registers. While everything about this mute is high-quality what really makes it special is the extra-long cork pads along the sides of the mute - not only do these ensure the mutes grips to the bell of your instrument but they also remove any noise from inserting or removing the mute. To ensure that it remains firmly in the right position it boasts a unique stay in place stem system for additional grip.
