Love It!

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.

Backun Fatboy+ Cocabola

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!

Fattening the sound with Fatboy

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.

Backun Fatboy Barrel

I liked this product so much that I bought a second to give to my music mentor as a gift, and he was equally impressed.

Nice sounding barrels

I recently purchased two fatboy barrels (66 and 67). They have improved my sound and intonation. I would highly recommend Backun barrels.

The best Barrel ever!

The barrel is phenomenal and can fill a concert hall with ease. It has a really loud yet sweet tone like no other!
