Justin Chart Syos Bari Sax Mouthpiece

Syos mouthpieces are made using a proprietary material developed as an alternative to traditional hard rubber and metal — dense, resonant, and precisely machined to tight tolerances. The result is a mouthpiece that combines the warmth of hard rubber with the projection and durability of metal, in a design that holds its dimensions consistently over time.

This is the Justin Chart signature model — a collaboration between Syos and the French baritone saxophonist known for his full, powerful sound and versatility across jazz and contemporary contexts. The specs reflect a setup built for players who want presence and depth without sacrificing control.

The tip opening is 0.105" (7) — a medium-wide opening that gives enough flexibility for dynamic range and expression while remaining approachable for players with a developed embouchure. It suits baritone players working in jazz, funk, and commercial settings where a projecting, focused tone is the priority.

Syos signature mouthpieces are produced in limited runs and tend to move quickly. If you've been looking for a high-quality baritone mouthpiece with a distinctive character and a well-considered spec, this is worth your attention.
