The Z was born of Yamaha's long and close partnership with the legendary trumpeter Bobby Shew. Bobby is an incredibly versatile player, and to meet all his playing requirements he wanted to create one super-efficient instrument which could scream out a powerful lead, or play soft, mellow ballades. When Yamaha decided to try to improve the Z, R&D specialist Bob Malone worked together with Bobby to create the ultimate horn for the legendary jazz player! In Silver plate.
