This pre-owned S.E. Shires C Taper bass trombone tuning slide, crafted from yellow brass and drawn tubing, is part of the Custom Series and fully compatible with all Shires Custom and Q Series bass trombone components.
It received a complete shop service here at The Brass Exchange, including a chemical bath, detailed inspection, and polish. The slide was in excellent condition at the time of sale—free of dents, dings, or repairs—with a clean and bright lacquer finish. Outer tubes were smooth, perfectly aligned, and ready to play.
The C Taper is known for its more gradual taper profile compared to other Shires options. This design produces an open, free-blowing feel that many players favor for better airflow and flexibility, especially in the low register. It pairs exceptionally well with various valve sections and bells, including the complete Q Series line, and has been praised by professionals for “opening up” their horn with improved resonance, response, and articulation in ensemble settings.
New, a Shires Custom Series C Taper tuning slide retails for around $435 in 2025. Pieces like this in such clean condition are not often available on the pre-owned market.
This tuning slide has been sold and is now part of our historical archive for reference by players, collectors, and enthusiasts.
