Inspired by the most prized, vintage mouthpieces of the 1920s, the Reserve Bb Clarinet Mouthpiece harnesses modern technology, pioneered by D’Addario, to recreate the incomparable craftsmanship found in these legendary works of art. Milled—not molded—from hard rubber for a higher level of consistency, every Reserve mouthpiece is machined to the strictest tolerances. But make no mistake: the true beauty of Reserve lies beyond its polished angles, glorious curves and proprietary materials to something far more remarkable… its sound.
