Versatility defined
The Fatboy is at home in the world's most prestigious concert halls, famous jazz clubs, and everything in between. It's our best-selling barrel, and for good reason. Artists who are called upon to interpret a wide variety of music appreciate the Fatboy Barrel’s unique flexibility and versatility. Note: In Japan, this model is known as the Backun Barrel.
Specs: Grenadilla or cocobolo wood. Compatible with Bb and A clarinets.
Fit
Most instruments use Standard fit. Standard Plus is the same fit with a larger bore that's more free blowing. Many (but not all) Selmer Paris instruments use Selmer Paris fit.
Length
Most clarinets use a 66 or 65 mm barrel, but this varies by manufacturer. If you're happy with the tuning you'll want to order the same size as listed on your current barrel.
Wood
Cocobolo is red in appearance and offers a dark, full-bodied tone. Grenadilla is brown or black and offers a more focused sound with increased ping and projection.

From the moment I started to use the barrel on my clarinet I felt the response change. My sound was bigger and brighter but still able to slide down to soft easily. Intonation was even throughout the range including the Altissimo. Highly recommend this upgrade
My first impression is that it does deliver what it says ! I have a simple student clarinet and thu barrel did wonder to upgrade the sound so much. Can’t wait to use it on an actual wooden clarinet !! Definitely recommend it and will buy other barres as well!
It has a lovely sound and really punches up the volume on my Yamaha.
I ordered the fat boy barrel and vocalise mouth piece and love my new sound and how easy it is to play with the legere synthetic reeds.
I recently purchased a Backun Fatboy+ barrel in cocabola to pair with my Buffet R13 clarinet and Vandoren 5JB mouthpiece. Wow! This barrel really opened up the sound and responsiveness of my horn. Being primarily a saxophonist, I'm used to more open mouthpieces and free blowing response. With the Backun Fatboy, switching from sax to clarinet is much more comfortable and natural feeling. The stuffiness is gone, and I feel like I have a setup that responds the way I'm used to having my saxes respond. I HIGHLY recommend checking out the Fatboy barrel if you're looking for a more open, responsive experience with your clarinet. Great work, Backun!
The Fatboy large-bore barrel added to my Buffet R-13 reduces resistance, improves midrange tone, and overall increases the instrument's projection. As a sax player doubling on clarinet, usually in large groups, I really appreciate all of these enhancements.
