Conn Helleberg 120S Tuba Mouthpiece

The Conn Helleberg 120S is one of the classic standard tuba mouthpieces, known for its deep Helleberg-style cup and focused response. Compared with many bowl-shaped tuba mouthpieces, the Helleberg design is often chosen by players who want a clear, centered sound with strong core and projection, especially in concert band, orchestra, brass ensemble, and school low brass settings.

This mouthpiece is a common upgrade or replacement choice for advancing tuba players, school programs, and players who want a reliable, widely recognized tuba mouthpiece. Conn-Selmer lists the 120S as a silver-plated tuba mouthpiece, and retailer listings commonly describe it with a medium-depth 120S cup and round rim.

Please note that all mouthpiece sales are final-no returns or exchanges are accepted-but we offer demo mouthpieces in store so you can try before you buy and find the perfect fit for your playing style.
