This is a used Reserve X5 mouthpiece for Bb clarinet. The piece shows a little bit of cosmetic character for past used but is in great shape overall. Its facing profile is in great shape as is the rest of the body. The beak is currently protected by a black Runyon mouthpiece patch.
Designed in the spirit of the best vintage hard rubber mouthpieces the Reserve is a master work in collaboration of ingenuity and craftsmanship. Each Reserve mouthpiece is milled out of hard rubber as opposed to coming from a mold. The milling process allows for a better end product which is much more consistent.
The D'Addario Reserve is an outstanding mouthpiece for the professional and progressive student.
