Developed with John Hagstrom New bell design: The newly designed bell features a new design that is narrower toward the pistons and a squared-corner U-shaped crook that provides the performer with an ideal blowing resistance. This results in a richer sound with a strong tonal core that improves upper register playability. The wall thickness gradually tapers, thinning as it gets closer to the rim. The flat rim helps hold sound together even at extreme dynamic ranges. Leadpipe: Utilizing an original Malone Pipe™ (MC1) for a leadpipe and a shallower mouthpiece receiver, we've achieved improved tone and response while providing the performer with an ideal blowing resistance.Malone Pipe™Based on leadpipes designed by renowned brass instrument artisan Bob Malone, the Malone Pipe™ is available in several keys, offering quick response, superior intonation and unparalleled evenness of tone: Originally a trumpet player himself, Bob Malone opened his own custom brass shop in Los Angeles in 1983. Trumpeters flocked to his shop to have him personally customize their horns. His original leadpipe design has enjoyed wide acclaim and is still held in high regard among trumpet players. Since Bob joined Yamaha’s Research and Development team in 2001, his Malone Pipe™ design has made its way into a number of Xeno Artist models and Custom series instruments. Rich and brilliant tone with excellent projection, the Malone Pipe™ brings total expression to your music. Improved response and ideal blowing resistance Redesigned parts, such as lighter weight pistons and valve casing, a semi-square crook shaped tuning slide and water key spring, result in improved response and provide the performer with an ideal blowing resistance. The first valve slide: The first valve slide features a special brace which gives a stronger focus to the core of the tone for unparalleled definition and clarity. Comes with Yamaha Xeno double case.
