The original “Z” was born of Yamaha’s long and close partnership with legendry trumpeter Bobby Shew. Then in 2018 Yamaha and Shew collaborated to create a second-generation YTR-8310Z that further refines the brilliant tone and well-balanced playing resistance that contemporary styles demand. The Shew ideal is one versatile, efficient instrument that can wail out powerful leads and also play soft, mellow ballads. The Z satisfies all of his playing requirements. The tapering thickness of the handmade bell gives players a very open and comfortable response as well as better feedback into their sound. The flat-dome bell rim helps players create their own personal tonal colors.
