CHI Brass Jacobs 2 Heavy Tuba Mouthpiece

The Classic Jacobs' Sound with Added Stability and Presence

The CHI Brass Jacobs 2 Heavy Tuba Mouthpiece builds upon the legendary Jacobs 2 design by incorporating additional mass to enhance stability, projection, and tonal density. Players who love the sound concept of the original Jacobs 2 often find the Heavy version provides increased security in demanding performance situations while maintaining the warmth, flexibility, and musicality that made the original famous.

The additional mass helps reduce unwanted vibrations in the mouthpiece, producing a more centered sound, greater slotting security, and a powerful tonal core that excels in large ensembles and orchestral settings.

Heritage and Design

Based on the same historic Jacobs-inspired design as the Jacobs 2, the Heavy version preserves the characteristic breadth and resonance associated with Arnold Jacobs while adding greater stability and projection for modern performance demands.

The result is a mouthpiece that offers exceptional consistency from the lowest register to the highest range while maintaining remarkable flexibility and tonal beauty.
