The same digital technology used for trumpet mouthpieces is now available for trombone. You can now use the same rim for all your playing needs. Up to 3 different cup depths are available to help you tailor your sound to the setting. The heavier Curry Blank requires a slightly larger throat and backbore than standard. The extra mass allows for a denser, richer tone and better projection.
S cups are slightly shallower than Bach C cups and produce a sparkling, compact sound. Good for commercial and big band lead work.
C cups are based on an old New York design. Excellent for all-around work.
M cups are slightly deeper and more conical than the C cups. You can attain a deeper, richer tone when it's required.
G cups are the “standard” for symphonic tenor. More cup-shaped than conical, you can achieve a variety of tone colors with this cup.
D cups are designed for orchestral tenor and bass trombone where a dark, powerful tone is preferred. D cups also can be used with great success on the euphonium. Diameters are equivalent to industry standards.
Cup Diameters are measured .065" from the top of the rim to allow for average lip intrusion into the mouthpiece. Stock models are offered in small and large shanks for the player who routinely switches from tenor to large tenor or bass trombone. Euro "mid-size" shanks are special order. Throats and backbores are adjusted accordingly.
