Legends Brass has partnered with KGUbrass to offer mouthpiece boosters. Use a booster to add core, color and depth to your sound. The added mass on your mouthpiece helps lock in slotting and clean attacks. And all with the added bonus of looking cool! KGUbrass has created an exclusive style booster available only through Legends Brass. In addition, we sell several styles from the KGUbrass catalog. What an innovative way to change your look and improve your sound!

Check out this video documenting how boosters change your sound.

More about boosters:

Simply slip your current mouthpiece into the booster. If needed, fit the booster precisely to the rim using the built-in adjuster.


Boosters fit seamlessly with Legends Brass lightweight, standard weight, vintage and Las Vegas Showroom blanks. They may work with mouthpieces from other manufacturers, as well.

KGUbrass boosters will not fit the following Legends Brass blanks: heavyweight, Big Daddy, Powerblank, JT, and Spotlight. They also will not fit mouthpieces with larger (higher mass) blanks from other manufacturers.
