The YTR8335LA Series Custom Bb Trumpet was developed in cooperation with famed LA studio veteran Wayne Bergeron. Designed for players needing an open instrument that is flexible and free-blowing, this trumpet takes the same bell of the Yamaha 8301Z trumpet and adds a large bore tuning slide and a Malone MB1 leadpipe. Perfect for the needs of both the soloist and the lead player in the trumpet section.
