CHI Brass JS Helleberg Tuba Mouthpiece

A Modern Interpretation of a Legendary Design

The CHI Brass JS Helleberg Tuba Mouthpiece combines the proven strengths of the classic Sear Helleberg design and modifications Jacobs had made with modern manufacturing precision and playability. Designed for performers seeking a large mouthpiece with clarity, broad sound, and low overtonal focus, the JS Helleberg delivers a powerful orchestral sound while maintaining flexibility across all registers.

Its balanced dimensions provide a comfortable feel for those preferring a flatter rim with a sharper edge and excellent response, making it a favorite among performers who require consistency in a variety of musical settings.  For those wanting this mouthpiece with a more rounded rim our JCS model is essentially the same but with the Floyd cooley rim. 

Design Philosophy

The Helleberg design remains one of the most influential mouthpiece concepts in tuba history. The JS Helleberg builds upon this tradition by providing a clean articulation response, focused sound core, and excellent projection while maintaining the warmth and musicality demanded by today's performers.
