Looking for a clarinet mouthpiece with vintage tone and modern consistency? The D'Addario Reserve X5 is inspired by classic 1920s designs but made with today's precision technology. It's milled—not molded—from a special proprietary hard rubber, which means every mouthpiece is incredibly consistent in shape and response. The medium facing (X5) is versatile, suitable for a wide range of playing styles from classical to jazz. Since it's machined to tight tolerances, you get accurate facings and smooth rails right out of the box, no hand-finishing needed. Made in the USA by D'Addario, a leader in woodwind accessories, this mouthpiece is trusted by pros and students alike. If you want a warm, resonant sound with excellent control and articulation, the Reserve X5 is a fantastic upgrade from standard mouthpieces. Just pair it with your favorite reed and feel the difference.
