.631″ WB S Trumpet Mouthpiece $115.00 – $140.00 The Legends WB S has a semi-flat wide rim with a soft comfortable bite and high alpha angle. The inside rim diameter (0.631”) is a little on the small side, and combined with the medium shallow cup depth works well for lead and upper register parts. This mouthpiece is geared toward lead and solo playing with plenty of zing in the upper register, but with enough mass to give the sound plenty of core. Select options
