Conn Helleberg 170 Euphonium Mouthpiece

One of the preeminent low brass players of the early 1900s, August Helleberg cultivated a close working relationship with Charles G. Conn. As the chief tubaist of the Sousa Band, Helleberg needed a mouthpiece that could give him the volume required to fill the largest of concert halls. After much experimentation, Conn and Helleberg masterminded the design to accomplish his goal. Today, his legendary sound lives on with C.G. Conn’s Helleberg Series mouthpieces. The 5E Euphonium Mouthpiece features a deep cup for a rich, symphonic quality. Sweetwater especially recommends the C.G. Conn Helleberg Series 5E Euphonium Mouthpiece for players in need of extra volume and a more expansive lower register.
