World renown artists, the likes of Tommy Dorsey, Ziggy Elman, Julian "Cannonball" Adderley, Charlie "The Bird" Parker, and Harry James, all trusted King as their choice of musical instrument. Built in Eastlake, Ohio, today's King 3B trombones continue in that tradition offering the best in professional level playing characteristics well suited for all musical styles.

The King 2103F "3B" is medium bore F attachment trombone with a traditional wrap. It features a .508" bore for excellent projection and open upper range with an 8" professional yellow brass bell that offers a quick response with a subtle brilliance. The chrome plated nickel silver inner hand slide tubes provide the ideal surface for smooth and quick hand slide action while the lightweight nickel outer hand slide provides a light and quick response. The clear lacquer finish adds a subtle warmth overall.
