Backun's first after-market clarinet bell was a revelation to those who played it: simple, refined, completely uninhibited. Developed with a custom wooden tenon ring to increase vibration, the traditional bell provides unparalleled response to your instrument. The optional Backun voicing groove improves the clarion register while aligning the break, an inherent challenge in some clarinets. Adaptable to both Bb and A clarinets.
