The Rod Franks Signature Series Trumpet Mouthpiece's medium-sized rim diameter and cup make it a very versatile mouthpiece. It produces more sound for the amount of air for more efficient tone than most orchestral mouthpieces. The tone is focused yet rich and full. The Franks mouthpiece features a large throat for a powerful orchestral sound, yet remains easy to play and is equally well-suited as mouthpiece for students. Silver-plated.

Rod Franks played with the legendary Black Dyke Mills band before beginning his long orchestral career, eventually becoming principal trumpet of the London Symphony Orchestra.

Yamaha's Signature Series mouthpieces come after years 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 of these mouthpieces. Each Signature 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.
