Yamaha signature series Bobby Shew mothpieces have become the lead player's dream mouthpiece! The Signature Series mouthpieces are exactly the same as those used by the artists whose name appears on them, and they embody the wisdom and expertise of these musicians in their design. Each of these models is produced on a precision computer-controlled lathe, guaranteeing that each one is exactly the same as the one used by its namesake. Bobby Shew's flugelhorn mouthpiece was designed at the same time Yamaha produced the YFH-6310Z flugel, and this mouthpiece perfectly complements the instrument. It features a semi-round and semi-thick rim, a deep cup and a specially designed backbore. The combination produces a smooth dark sound and exceptional playability.
