D’Addario Woodwinds Reserve Bb Clarinet Mouthpiece, X0 (MCR-X0)

I went to open the mouthpiece box and the whole mouthpiece fell out of the bottom of the box. No wrapping, no tape to keep the box closed—NOTHING. An open mouthpiece sitting in an open box with no protectiion. For $100, D’addario should be ashamed of themselves—or Amazon should. Packaging terrible, playability second to none. This is my favorite mouthpiece. What a beautiful sound, double p like never before.

Fantastic mouthpiece. I would recommend it to every single clarinetist looking to develop a professional tone quality, or a professional who would love a nice, versatile, and controllable mouthpiece for the demands of the classical universe. Articulation is so much easier to emphasize, and it overall beats the Vandoren mouthpieces by a longshot. This piece is also more durable than the Vandorens, because my M13 lyre chipped within the first week of getting it, but the Reserve X0 has held to the day.

This is a great mouthpiece for a person who is looking for an affordable upgrade. I purchased this mouthpiece during my freshman year of my undergraduate degree. After I started playing on the D'Addario (formerly Rico) Reserve Mouthpiece, I was able to develop a rich tone and extend my range significantly. I tested several of these mouthpieces before making my purchase and I found them all to be very consistent. I felt like I knew precisely what I was purchasing even without playing the exact mouthpiece I was getting from Amazon.com.

I recently began playing the clarinet again, and was having some trouble with my old 5RV vandoren mouthpiece. I ordered the Rico Reserve X0 to try something with a longer facing and narrower tip and I have not been dissapointed. I've tried it with a variety of reeds and settled on Vandoren 56 Rue Lepics. In short, the mouthpiece produces a wonderful tone with nice intonation and responsiveness. While mouthpieces are a rather personal choice, and what works for one player may or may not work for you, they're certainly worth trying out if you're in the market for a new mouthpiece. And for the performance they provide, they're rather a bargain.

The X5 model is the best overall clarinet mouthpiece I have ever used. It plays amazingly even throughout all registers. I have had students test play this mouthpiece against other popular models from Vandoren, Fobes, etc... and every single one has chosen the D'Addario X5.

My time on the clarinet is limited to approximately two years. I've always had trouble getting the sound I want - or, in many cases, any sound at all with a 2.5 strength reed on the mouthpiece that came with the clarinet. With the first breath through this mouthpiece, I got the sound I wanted...consistently. I never realized how much difference a "specialty" mouthpiece could make.I'm now convinced!

Great mouthpiece! The tone is darker than other mouthpieces. Well-rounded and works awesome for all kinds of music. 10/10 recommend.

I needed to replace my old Morgan mouthpiece and heard that this was a good one. I already love Grand Concert and Rico Reserve reeds, so it was exciting to try a mouthpiece from the same company. Excellent response and clarity of sound. I'm looking forward to getting to know this mouthpiece even better with lots of use.
