King 3B Legend Professional Tenor Trombone

The King 3B is a professional straight tenor trombone built around a classic small-bore jazz concept, prized for its agility, control, and signature King clarity. With a .508 bore and an 8-inch yellow brass bell, it delivers quick response and a centered tone that speaks immediately in every register. This is an open-box instrument we guarantee to play like new, offering meaningful savings on one of the most established performance standards in the trombone world. A lightweight nickel silver slide supports fast technique and clean articulations for lead, section, and solo work.

Players choose the 3B for its focused projection that cuts in amplified settings while remaining refined for acoustic work. The yellow brass bell emphasizes speed of response and tonal definition, helping notes lock in with minimal effort. The .508 bore supports accurate pitch center and flexible dynamics, from bright lead playing to a warm, compact section sound. The lightweight slide design enhances clarity and reduces resistance for quick shifts and tight rhythmic precision. It’s an ideal fit for jazz lead and section players, commercial musicians, studio artists, and advancing students stepping into a true professional instrument—protected by a hard shell case and backed by an authorized King dealer.
