Reserve Evolution Mouthpieces harness 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. Of course, the true beauty of Reserve lies beyond its polished angles, curves, and proprietary material to something far more remarkable: its sound.

Introducing D’Addario Reserve Evolution Bb Clarinet Mouthpieces. Designed for the modern clarinetist, Reserve Evolution mouthpieces deliver a warm and refined tone featuring quick response and ease of articulation. This new mouthpiece from D’Addario Woodwinds provides clarinetists with greater flexibility for a wide variety of musical styles.

• Precision milling delivers unparalleled consistency, eliminating the need to try many before purchase
• Revolutionary ramp and bore taper geometry for fuller, more centered tone
• Altered baffle for added projection and articulation nuance
• Medium-long facing for greater flexibility
• Expertly-designed and made in the USA from imported materials by a team of top musicians and engineers
• Offered in two different pitch systems--440Hz, and 442Hz

Please choose the pitch required. 442 is a bit sharper that 440. We would suggest 442 for Europe. If you tend to play on the sharp side then 440 would help you to play a bit flatter.
