Unleash a deep, rich, and truly characteristic euphonium tone. Developed in collaboration with legendary euphonium soloist and pedagogue Dr. Brian Bowman, and meticulously manufactured under the Griego umbrella, the Brian Bowman (BB) Series is designed to help players achieve the ultimate core of sound, outstanding intonation, and effortless response.

Whether you are a seasoned professional, an advancing student, or a young player looking to step up from a standard trombone mouthpiece, there is a Bowman model engineered specifically for your needs.

• The Sound: Deep, rich, and resonant—perfectly tailored to the demands of modern euphonium performance.

• The Design: Features a deep cup and a large backbore.

• The Performance: Specifically engineered to provide superior center of sound and outstanding, reliable intonation across both the extreme high and low registers. This is the primary model played by Dr. Brian Bowman himself.

• Specs: 25.00 mm Rim Diameter | 7.00 mm Bore

• The Sound: A full, exceptionally responsive, and traditional euphonium sound.

• The Design: Patterned after traditional classic euphonium profiles, featuring a responsive "V" cup design. While not as deep as the BB1, it still retains a wonderfully warm, characteristic tone.
