Reserve Bb Clarinet Mouthpiece

Good vintage clarinet mouthpieces from the 1920s are hard to find and harder to trust. The best ones play beautifully — warm, centred, responsive — but they're inconsistent by nature. Every piece came off a different set of hands, and two mouthpieces with the same model name can play completely differently. The D'Addario Reserve was built to solve that problem.

Milled from solid hard rubber using CNC machining — not molded — each Reserve is cut to tolerances that hand-finishing can't match. The geometry is the same piece to piece, which means you're not sorting through a box hoping to find a good one. You order a Reserve and you get exactly what the design calls for, every time.

The tone sits in warm, focused territory — full in the middle register, even across the breaks, with throat tones that speak more freely than on many comparable mouthpieces. It's a sound that works in concert band, wind ensemble, and orchestra without asking you to fight the equipment. Articulation is clean and quick, and the medium-long facing gives you flexibility in how you shape the reed and approach different styles.

Available in multiple tip openings to suit different players and playing situations. The X0 and X5 are the most popular choices for students and advancing players — practical facings with easy response and a warm, focused sound. Larger openings suit players who want more flexibility and dynamic range.

Made in the USA. Pairs naturally with D'Addario Reserve Classic reeds for a well-matched setup right out of the box.
