This model is inspired by one of those traditional mouthpieces with which we all started. For many players, the Bach mouthpieces are the foundation of the mouthpiece world. Legends Brass has taken these classics and added a modern twist! The rim on the 10 1/2 C is semi-round, with some undercut for chop room. The cup is medium depth. Although the rim and cup are similar to the original, this is not an exact copy. The Legends 10 1/2 C has been improved with the Legends enhanced #27 throat, enhanced throat cylinder length, and Legends S backbore. Try it in the heavyweight blank for the best slotting, superior core, and excellent projection.
