Fatbay Barrel help the entonation of my clarinet in all weather and temperatures

The new Fatbay Barrel granadilla help me to improve the entonation of my clarinet in Bb and A in all weather (humid) and temperatures (extremilly warm) in San Germán, Puerto Rico. Also, I am very happy with the projection and the tone quality. Congratulation for the quality of your products.

Expectacular Barrilete Fatboy Cocobolo

The Barrels is wonderfull. A warm sound, very focus in the lower register and very accurate in the alto and alttismo register very tune. I am falling in love. My clarinet is an old Buffet E11 and the mouthpiece is a viotto B5L.

Quality

The workmanship of the Fatboy barrel is impressive. Still evaluating the difference on my 1976 RC Buffet Crampon.

Selmer Fit Fatboy Barrel

I have a VERY old Selmer A clarinet that was in need of a barrel upgrade and this did the trick! I was nervous it wouldn't fit due to my clarinet's age, but it did! I purchased the longest barrel available and still need to pull out a considerable amount, but this may not be necessary for everyone. Highly recommend!

Great Barrel!

I tried out several barrels and ended up choosing the Fatboy in cocobola wood. The barrel gave an extremely noticeable difference in dynamic range and projection power that even the Fatboy in grenadilla did not seem to have (without more effort). The barrel was free-blowing and had a beautiful, warm, dark tone. I will probably never play on my stock Protege barrel again, I liked it so much! It was a great investment for me.
