Crafted in close collaboration with Hiram Diaz — one of the most celebrated euphoniumists in the world, a second-generation Cuban-American powerhouse, and a key voice in the legendary President's Own United States Marine Band since 2012 — this signature mouthpiece is engineered for the moments that matter most: high, extended solos that demand to be heard, felt, and remembered. While Hiram's daily setup handles the full spectrum of Marine Band duties (concerts, ceremonies, marches, and more), this mouthpiece is his specialized solo dominator — the one he reaches for when the spotlight shines, the melody soars into the stratosphere, and every note needs to project with crystal-clear resonance, pure tone, and uncompromising clarity. The refined geometry delivers effortless upper-register access, a singing lyrical quality, and a focused core that blooms beautifully in any hall — whether performing virtuosic concertos, lyrical features, or standout passages in the nation's premier military ensemble.

Why this mouthpiece elevates your playing:

• Exceptional projection — Cuts through large bands or orchestras with ease, ensuring your solo voice stands tall without strain
• Pure, resonant tone — Warm, centered, and vibrant — ideal for expressive highs that captivate audiences
• Effortless extended range — High notes feel open, secure, and musical, perfect for demanding solo literature
• Comfort & response — Stainless steel efficiency transfers your air instantly for quick articulation, dynamic control (from delicate pianos to powerful fortes), and reduced fatigue during intense solo work
• Versatile solo focus — Blends seamlessly in ensemble settings yet commands the front when needed

Hiram Diaz doesn't just play euphonium — he inspires. This mouthpiece captures that same artistry: built for players who want to step into the light, deliver extended, soaring lines with confidence, and leave every listener moved by a sound that's pure, powerful, and unforgettable. If you're chasing solo brilliance — whether in recitals, concerts, competitions — the Hiram Diaz Signature is your go-to.
