Yamaha YSL-456G Intermediate Tenor Trombone.
This model was originally produced for the Japanese domestic market, with the U.S. equivalent being the YSL-446G, which today sells new for well over $2,000. Its limited availability outside Japan makes the 456G an appealing find for players seeking Yamaha’s renowned intermediate-level craftsmanship.
The horn features an 8″ gold-brass bell that offers a slightly warmer, broader tone compared to standard yellow-brass bells — a feature often appreciated by advancing students moving up from straight small-bore models. It includes a standard-wrap rotary F-attachment and a dual-bore .500″/.525″ handslide, bridging the gap between entry-level student horns and full-size .547-bore professional instruments.
This example has been professionally cleaned and serviced in our shop. It shows no history of damage or repairs, having been owned by a single careful player. Cosmetic signs of use are minimal. The slide is smooth, properly aligned, and ready to play; the valve is clean and responsive. It includes the original Yamaha case, mouthpiece, and a fresh set of lubricants for both slide and rotor — making it genuinely ready to play right out of the box.
The 456G is an excellent choice as a first trigger horn for a middle- or high-school trombonist who is not yet ready to step up to the larger, heavier .547-bore symphonic models. Its manageable size and high-quality build give advancing students the tonal flexibility to participate in both concert-band and early jazz or small-ensemble work.
This particular instrument has been sold and is preserved in our archive as a trusted reference for educators, students, and collectors researching Yamaha’s intermediate trigger trombones.
FAQs
How does the YSL-456G compare to the U.S.-market YSL-446G?
The two models share the same design and playability; the 456G is essentially the Japan-market version and is rarely seen in North America.
Is the dual-bore slide good for advancing players?
Yes. The .500″/.525″ bore provides a smooth transition from small-bore student horns to larger symphonic trombones, giving more tonal breadth without demanding excessive airflow.
What advantage does the gold-brass bell provide?
Gold brass typically offers a slightly warmer, richer tone compared to yellow brass, which many players appreciate when developing a more mature sound.
Why is this model recommended as a first trigger trombone?
It introduces students to the ergonomics and expanded range of an F-attachment without the weight and air demand of a .547-bore horn, making it ideal for this level.
