While maintaining many of the design features that made the original Custom Z trumpet so unique, the new YTR-8310ZII has an updated leadpipe and a precise valve casing design. These modifications combine to offer unprecedented tonal richness and depth, while maintaining maximum efficiency and comfortable resistance for players in any setting and genre from the jazz club stage to the recording studio.
