The Yamaha YTR-8310Z Bobby Shew Custom is a result of Yamaha’ s partnership with the great trumpeter Bobby Shew. As a lead player in a big band or in a largely soloing context in a quintet setting, Bobby Shew had a vision of creating one single instrument that could do it all. He finally found that instrument in the custom Z.
When Yamaha decided to try to improve the Z, trumpet designer Shunichi Niwata and R&D specialist Bob Malone worked together with Bobby, making sure it had what Bobby needed in order to handle all of these various applications.
The result was the Z as it is today. Key of Bb. Lightweight; .445″ bore; one-piece, 5″, yellow brass bell; one piece, drawn, gold brass mouthpipe; Monel pistons; hand-lapped pistons and slides; laser-fused pluzuma welded bell; unbraced inner outer tuning slide; large bell flare; large bore tuning slide; and special bead and bell taper.
