King 3BPL Tenor Trombone Overview
The King 3BPL Legend professional tenor trombone gives players a medium-bore King option within the well-regarded 3B family. King 3B trombones have long been associated with clear response, articulate slide technique, and strong commercial and jazz usefulness, while the 3BPL adds a 0.525 inch bore for players who want additional breadth without moving into a large-bore symphonic setup. This instrument offers that 3BPL concept in lacquer with the practical support of a fitted case and included playing accessories.

Who the 3BPL Tenor Trombone Is For
The 3BPL is well suited to trombonists who want the immediacy and clarity associated with the King 3B lineage, but with the added breadth of a 0.525 inch medium bore. It is a strong fit for commercial playing, jazz ensemble work, pit orchestra use, teaching, and section playing where a centered, articulate tenor sound needs to project without the weight of a large-bore orchestral trombone.
Common Questions About the King 3BPL
How does the King 3BPL differ from a standard King 3B?
The standard King 3B is built around a 0.508 inch bore, while the 3BPL uses a 0.525 inch bore. That gives the 3BPL a broader response and a little more tonal weight while preserving much of the direct character players expect from the 3B family.
What musical settings suit the King 3BPL best?
The 3BPL is especially useful for players who move between jazz, commercial, show, studio, and ensemble settings. Its medium-bore design gives it flexibility for lead, section, and crossover work where a large-bore orchestral trombone is not the desired sound.
Why does the small-shank setup matter on this trombone?
The included Bach 7C small-shank mouthpiece keeps the setup aligned with medium-bore tenor trombone playing. Players who already use small-shank tenor mouthpieces will have a wide range of familiar options for tailoring response and sound.
