D’Addario Reserve Clarinet Mouthpiece
Precision CNC Machined in the USA
To create the world’s first 100% precision-milled, vintage-inspired clarinet mouthpieces, you need three things: a team of the nation’s foremost clarinetists and craftsmen, a company dedicated to technological innovation, and the unwavering determination to build something legendary. The end result is the D’Addario Reserve Clarinet Mouthpiece.
Inspired by the most prized, vintage mouthpieces of the 1920s, Reserve harnesses modern technology, pioneered by D’Addario, to recreate the incomparable mouthpiece craftsmanship of yesteryear.

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

Which Model Should I Choose???
This is the hard part. Everyone has a different opinion and view on these mouthpieces. For instance, a loner facing will make a mouthpiece feel more open than it is which gives the player the advantage of feeling free-er while still providing the improved articulation of the smaller tip opening. However, this also means that the player has to have more control over their embouchure and breath support. So, here is the opinion of our mouthpiece expert, Dave Kessler, on the various models:
Dave Kessler's Model Descriptions
Unlike the other models in the Reserve Clarinet mouthpiece line, the X10E uses a medium-short facing length (compared to medium-long or more). This allows for younger players to develop a richer tone with better response even if they have not yet mastered their embouchure control.
This model also features the E Series chamber which generally provides a quicker, livelier response for many clarinetists with decreased resistance. The smaller tip gives exceptional control throughout all registers. Compares favorably with the Vandoren 5RV Lyre (note that I rate this mouthpiece different than the manufacturer in this regard… these are personal opinions)
This model also features the new E Series chamber as well as a larger tip opening and much longer, “extra-long” facing. With a facing that is significantly longer than the other models (including the Vandoren models), the X15E gives an amazing balance of power and control. The 1.18mm tip opening is closer to the Vandoren B45 & B46 models but the longer facing gives it a power and feel closer to the 5JB jazz models. However, for many players, they will find this mouthpiece much more controlable through the range than the 5JB will be. The mouthpiece favors a somewhat softer reed (2.5-3) but leans toward reeds that have a thicker blank (Reserve Classic, Gonzalez FOF, V12 or 56 Rue Lepic). This is a very fun mouthpiece for the solo player or jazz musician.
This model also features the new E Series chamber with the largest tip opening of the line withthe “extra-long” facing. With a facing that is significantly longer than the other models (including the Vandoren models), the X25E gives an amazing power and and projection. The 1.25mm tip opening is closer great for players who prefer a softer reed and want as much power as their mouthpiece can afford but still need precision and control. The mouthpiece favors a softer reed (2.0 – 2.5) but leans toward reeds that have a thicker blank (Reserve Classic, Gonzalez FOF, V12 or 56 Rue Lepic). This is a very fun mouthpiece for the solo player or jazz musician.
