CHI Brass 4023 Helleberg Tuba Mouthpiece

4023 Helleberg Tuba Mouthpiece

The CHI Brass 4023 is meticulously crafted to occupy a unique position within our lineup, bridging the gap between the popular JS and Jacobs 2 Hellebergs. Here's what sets it apart:

• Rim Design: Retains the much-loved rim from the Jacobs 2 model.
• Interior Dimensions (ID): Enlarged from the Jacobs 2 and slightly reduced from the JS.
• Cup and Throat Combination: Features the cup shape of the JS with the throat and backbore of the Jacobs 2.

This design provides a balance of burly tonal characteristics akin to the JS Helleberg, while maintaining the ease of playability and the ability to achieve a growling low register, as seen in the Jacobs 2.
