Used Yamaha YSL-691 Tenor Trombone - Black Lacquer

Serial Number:  201837 

The Yamaha YSL-691 is a refined professional-level tenor trombone from a period when Yamaha was thoughtfully expanding its small-to-medium bore lineup. Positioned above entry-level jazz models, the YSL-691 was designed for players seeking added flexibility, balance, and consistency without moving into a full large-bore instrument.

Featuring a .508 bore lightweight handslide paired with an 8" yellow brass bell, this model sits comfortably between traditional .500 bore jazz trombones and larger medium-bore designs. The result is a trombone that offers clarity and quick articulation while providing extra breadth and stability for lead, section, and commercial playing. The black lacquer finish adds a distinctive visual presence while preserving the instrument’s focused, centered tone.

A standout design element is the fixed balance weight integrated into the tuning slide brace. Rather than a removable counterweight, this built-in system subtly shifts the instrument’s balance toward the player, contributing to comfort during long rehearsals and extended performances. This example includes three interchangeable leadpipes, allowing players to fine-tune response and feel to suit different musical settings.

This gently used YSL-691 comes complete with a mouthpiece and the original Yamaha factory case, making it an excellent option for advancing students, doubling professionals, or players seeking a versatile Yamaha tenor with classic design features.
