King 3B Tenor Trombone Overview
The King 3B Legend is a respected professional Bb tenor trombone with a long association with jazz, commercial, and section playing where clarity, flexibility, and projection matter. Its small-bore design gives players a compact response and a focused tonal profile compared with large-bore orchestral tenors, making the 3B a strong choice for players who want the classic King small-bore trombone concept.

Condition & Setup
This used King 3B is in excellent playing order and has been professionally serviced, set up, and play-tested by The Mighty Quinn Brass and Winds. The handslide is noted as good, an important functional point for a small-bore tenor trombone. Cosmetically, it shows scratches, scuffs, small dents, scattered lacquer wear, and worn spots around the slide receiver area. The included King-branded hard case has exterior wear from use.
Who the 3B Tenor Trombone Is For
The King 3B is well suited to advanced and professional players who want a responsive small-bore tenor for jazz, commercial work, musical theater, worship, solo playing, and lighter ensemble settings. Players who prefer a compact feel, clear articulation, and a focused sound will usually find the 3B more appropriate than a large-bore symphonic tenor; players primarily focused on large orchestral repertoire may prefer a larger bore instrument.
Common Questions About the King 3B
How does the King 3B fit within professional tenor trombone choices?
The King 3B is a professional small-bore Bb tenor trombone designed for players who value agility, clarity, and projection. It is commonly chosen for jazz, commercial, lead, and section work rather than large-bore orchestral applications.
What does the .508 inch bore contribute to the playing feel?
A .508 inch bore gives the 3B a quick, efficient response with a focused center to the sound. This bore size supports flexible articulation and helps the instrument speak easily in styles that require clarity and presence.
Why do many players choose a small-shank King 3B?
The small-shank setup keeps the instrument in the traditional small-bore tenor trombone family. It pairs well with mouthpieces intended for jazz, commercial, and lighter tenor work, where response and tonal definition are priorities.
