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.
