The Bolero is a shallow cup mouthpiece, perfect for most music played on your small bore (.500) tenor trombone and alto trombone. The shallow cup also would make this an excellent mouthpiece for high range playing on your medium bore tenor trombone.
As I begin to produce a variety of rims, they will be available for this model.
