The symphonic model of Roger Bobo's signature mouthpieces is characterized by a warm tone that's big enough to fill the concert with a rich, colorful sound. Fairly deep, roomy cup for a warm, big sound, and throat and backbore design give enough jump and snap for maneuvering through quick jazz passages with a rich, full sound. It's ideal for use with BBb and C tubas and helps enrich the tone of any ensemble. Silver-plated.

Yamaha's Replica Series mouthpieces come after year of collaborating with hundreds of the world's best players at their R&D Ateliers. These players were unsatisfied with the commercial models out there and knew the Yamaha technicians would deliver exactly the tone and response they wanted. The demand for these mouthpieces has grown, so Yamaha decided to offer a select lineup. Each Replica Series mouthpiece is produced on a precise, computer-controlled lathe to guarantee each one is exactly the same as the one used by its namesake.
