Inspired by the most prized, vintage mouthpieces of the 1920's, Reserve harnesses modern technology, pioneered by D’Addario, to recreate the incomparable mouthpiece craftsmanship of yesteryear. Milled—not molded—from hard rubber for a higher level of consistency, every Reserve mouthpiece is machined to the strictest tolerances.
