The S.E. Shires Custom Series .500/.508 Dual Bore Trombone is a rare and special-order configuration, offering the responsiveness of a small-bore horn with the projection and power of a larger bell. Built with the 7YM 8" medium-weight yellow brass bell (soldered rim), a TY 1.5 tuning slide, and a dual bore .500/.508 handslide with nickel silver end crook, this instrument plays with remarkable strength and versatility.
Unlike many Shires small-bore models, which feature 7.5"–7.75" bells, this example’s 8" bell allows for a broader sound with a strong core and fundamental. The dual bore handslide adds openness and flexibility, while the two included removable leadpipes (large shank) give players the ability to tailor resistance and response to their preference.
Condition is outstanding. This lightly used horn remains super clean with minimal signs of wear. The handslide is excellent — smooth, true, and ready for professional use with no service needs. The trombone also comes with a Marco Magi SR Artist Series backpack-style case, providing premium protection and portability for working musicians.
For style, this Shires plays exceptionally well in jazz and commercial settings, though it is flexible enough for symphonic pops and film score work. Its balance of agility, warmth, and projection makes it an excellent choice for the serious player seeking a top-level professional horn.
FAQ 🤔
Q: What makes the dual bore .500/.508 handslide special?
Dual bore slides start narrower (.500) at the upper tube and expand to a wider size (.508) at the lower tube. This provides a balance of quick response with added openness, giving the player more tonal breadth.
Q: How does the 7YM 8" bell differ from smaller Shires bells?
The 7YM bell is larger than most Shires small-bore options, giving the horn a bigger, more projecting sound. The soldered rim also adds focus and stability, making it comparable to classic Conn 88H-style bells but with Shires precision.
Q: Who is this trombone best suited for?
This setup is perfect for jazz and commercial players needing more power than a traditional .500 small bore, but it also works beautifully in pops and crossover settings.
