Archive Overview
The S.E. Shires Dual Bore valve section is a popular Custom Series option for tenor trombonists who want compact valve response while preserving the traditional tenor trombone sound. Built in the Boston factory, this design offers smooth action, clean articulation, and excellent tonal balance across the full range of the instrument.
Many players prefer the Dual Bore configuration because it keeps the valve body compact and responsive while maintaining a centered sound that blends easily in orchestral, chamber, jazz, or commercial settings. Compared with larger axial-flow or oversized rotor systems, the Dual Bore valve retains a familiar feel and consistent resistance that many tenor players find comfortable.
This example was factory-new inventory when originally offered. Like all S.E. Shires Custom Series components, it was fully compatible with past and current Shires bells, tuning slides, and handslides, allowing players to refine or expand modular setups with confidence.
Dual Bore valve sections remain a strong choice for musicians seeking reliable performance without moving to heavier or more specialized valve designs.
