Warburton One Piece Trombone Mouthpiece
Warburton were pleased to announce the arrival of their high quality one-piece trombone mouthpiece. It was due to the demand from many players who wanted a mouthpiece in size that they are familiar with. While the numbering system is familiar, (using Bach nomenclature), each model has been designed to eliminate problems that have come to light over the years. Warburton have made the rims more comfortable, and the throat sizes are balanced to the cups. The back-bores are maximized for tone production and projection.
