Munnstykke Trompet Yamaha Bobby Shew Jazz

Yamaha TR-SHEW-JAZZ Mouthpiece for Trumpet 'Bobby Shew - Jazz'
Signature Series

Overview
Though its a fact little known outside professional circles, Yamaha has been producing special custom-made mouthpieces for hundreds of the worlds top players at our R&D Ateliers for many many years.
These artists were not satisfied with any commercial models available. They came to us because they had confidence that if anyone had the skill needed to create their own dream mouthpiece, it was Yamaha.
The players knew from the experience gained in their long careers exactly the kind of sound and response they wanted, and our technicians knew from their long experience in crafting instruments how to deliver it.

More and more colleagues and students of these top players began to ask us for copies of the mouthpieces, so we decided to offer a select lineup of them in a new Signature Series.
Now others can share in the results of this great cooperative effort between artist and artisan.
