Long Facing, European Pitch
MCR-X25E
ORCHESTRA, CHAMBER, SOLO
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.
As vintage mouthpieces become more expensive and increasingly rare, clarinetists are running out of options for well-made, great-sounding mouthpieces. Reserve mouthpieces are the answer. They give every player access to the inspiring vintage tone they need to sound their best.
