Thanks to Bobby Shew's close collaboration with Yamaha, lead trumpet players now have the perfect trumpet mouthpiece. The Bobby Shew Lead Trumpet Mouthpiece has a precise response to high notes. High Notes can be played safely. Due to the narrow backbore and the very flat bowl a bright, open sound with a lot of projection is achieved. The medium-wide edge ensures good endurance. The inner diameter of Yamaha's Bobby Shew Lead Trumpet Mouthpiece is 16.54mm and the bore is 3.56mm.
