Founded in Cleveland (Ohio) at the end of the 19th century around Henderson White and the contribution of trombonist Thomas King, the King brand quickly stood out with an innovative approach to the bore, the bell, and especially a slide known to be smoother and lighter than the competition. This pursuit of playing comfort and acoustic efficiency contributed to the brand's reputation among professional musicians, then to its popularity in big bands and orchestras over the decades. The King 606 continues this tradition with a clear positioning: a solid, musical, and accessible study trombone designed to support long-term progress.
The King 606 is primarily aimed at beginners and intermediate players seeking a reliable, in-tune, and pleasant instrument under the slide. Its design makes it an excellent choice for conservatory, wind ensembles, brass bands, school orchestras, and early steps in jazz. Its versatility allows tackling both classical study repertoire (legato and intonation work) and more rhythmic playing (attack, articulation, swing) without feeling limited.
With its 203 mm brass bell, the King 606 offers a warm tonal color, consistent projection, and a strong presence overall. The 12.77 mm bore promotes relatively easy and stable sound production, which helps build tone, secure attacks, and improve intonation across all registers. In terms of feel, the combination of a chrome-plated inner slide and a yellow brass outer slide aims for smooth gliding and good durability, essential for working on legato and precise position changes. The lacquered finish protects the instrument and maintains a neat appearance daily.
The instrument is delivered with a Bach mouthpiece and a hard case. The most useful addition for regular maintenance is a slide lubricant (cream or suitable spray type) to preserve smooth slide action, as well as a soft cloth for the lacquered finish.
