Second-gen Bobby Shew Signature Trumpet The YTR-8310ZIIS Custom Z represents the second generation of Yamaha's acclaimed Bobby Shew signature trumpet. This horn's refined design not only supplies unparalleled richness and depth, but its well-balanced playability will also meet the ever-changing needs of modern players.

You also get a 1-piece side-seam bell with a French bead rim that maximizes this trumpet's resonance and projection. You'll appreciate the superior tone stabilization and heightened upper-register playability supplied by the YTR-8310ZIIS's extra-long third valve slide stopper screw, and how its silver-plated brass body lends a brilliant sheen to every note you play.
