Backun MoBa Clarinet Barrel
Barrels as unique as the artists who play them!
The Backun MoBa Clarinet Barrel produces a full-bodied dark sound that is incredibly flexible throughout the clarinet’s tonal spectrum. Ease of articulation in the upper range and exceptional sound quality are just a few characteristics of this collaboration between Ricardo Morales and Morrie Backun.
We find that the Backun MoBa clarinet barrel works best with more modern clarinets. We recommend the Backun MoBa clarinet barrel on the specific clarinets:
Buffet: R13 (made in 1990 and newer), R13 Prestige (1990 and newer), Festival, RC, RC Prestige, Tosca & Divine
For R13 models made prior to 1990, we recommend the Backun Fatboy barrel.
Yamaha: CSVR, SEV & SEVR Models
Leblanc: All France Models as well as the Leblanc by Backun models
Adaptable to both Bb and A Clarinets.
Additional Information
The Backun MoBa Clarinet Barrel is available in 2 different fit styles:
- Buffet / Leblanc / Yamaha Fit (excludes Yamaha CSG models)
- Selmer Paris Fit
Kessler & Sons Music stocks primarily models that will fit Buffet, Leblanc & Yamaha models. These models are easiest to identify by their size. The models made for the Buffet/Yamaha/Leblanc fit will be an even number in its length (66mm, 65mm, etc…) whereas the models made for Selmer Paris clarinets will be measured in half millimeter sizes (66.5mm, 65.5mm, etc…)
Backun does also offer a specially made model for the Yamaha CSG clarinets that are available on special order only.
The Backun MoBa Clarinet Barrel is available in 2 different woods: Grenadilla & Cocobolo. There are many differing opinions on which is best and even differing opinions on what the wood does to the sound. So here are the personal opinions of Dave Kessler in regards to these woods:
Grenadilla Wood
Grenadilla is the same wood that most clarinets are made out of. Backun uses a premium quality, unstained Grenadilla for the Backun MoBa clarinet barrel. I find that the Grenadilla will produce a more tonally centered and deeper tone that the audience will hear as darker and richer. Personally, I always prefer the way that customers sound on the Grenadilla as I listen to them. However, the effect of the wood “behind” the clarinet will make the player perceive the Grenadilla as a bit brighter and more focused than the Cocobolo wood.
Cocobolo Wood
Cocobolo is a very dense wood and like the Grenadilla, Backun uses a premium quality, unstained Cocobolo for the Backun Moba clarinet barrel. I find that the Cocobolo gives a broader and sweeter tone that is more open that the audience will hear as brighter and lighter. However, the player “behind” the clarinet will generally perceive the Cocobolo as the richer of the two because they are “hearing more” from the clarinet than they do with the Grenadilla.
Kessler & Sons Music offers a 3 day trial / return policy by default on any in stock Backun MoBa Clarinet Barrel. There are no cleaning fees or restocking fees (assuming that the item is returned in proper condition).
Before we ship any new Backun MoBa clarinet barrel, we actually inspect the barrel in the shop to ensure proper fit. We own full sets of Backun factory made reamers to check the tenon fits of the barrels. This ensures that the barrel should fit your clarinet. The barrel might be a hair loose compared to your barrel since your cork has likely compressed over time to your barrel. However, you can generally still test the barrel without much issue. If you do have any issues with fit, you can use a Teflon tape (also called Plumber’s tape) to wrap your cork to help provide a more snug fit of the barrel while not impacting the fit of your stock barrel. This Teflon tape can usually be purchased at your local hardware store for a very low cost.

Initially my clarinet was quite sharp so I decided to change the 65mm stock barrel to a 66mm. I was not certain weather to go with the FAT BOY or with the MOBA barrels. This is when I decided to contact Dave Kessler. He helped me make the decision to go with the MOBA 66mm barrel and I must say I am impressed and incredibly satisfied with my purchase.
I never thought that by changing the stock barrel of my Protege-Backun Cocobolo clarinet to the MoBa Cocobolo barrel would enhance the quality in sound reproduction and accuracy of tone as dramatically as it did. This improvement is noticeable throughout the whole register of the clarinet.
The warmth and richness in sound reproduction is just outstanding!
Kudos to Backun Musical Services for such a high quality product and thanks to Dave Kessler for his invaluable advice.
