📌 Archive Reference – No Longer Available for Sale
This S.E. Shires Custom Trubore independent valve section (Bb/F/Gb/D) is presented here as part of The Brass Exchange Archive of Sold Instruments — a valuable reference for bass trombonists researching one of Shires’ most advanced and sought-after modular components.
Hand-built in Boston as part of the Shires Custom Series, the Trubore valve system is widely regarded as the flagship independent valve design for serious bass trombonists.
Praised for its open feel, smooth response, and balanced resistance, it remains one of the most distinctive and in-demand designs in the Shires lineup.
✦ Condition at Time of Sale
This example was a post-2020 build and in like-new condition:
Only a few years old with very little play time
Flawless lacquer finish and precise, quiet valve action
Short-throw lever system for highly responsive control under professional demands
Factory-installed adjustable thumb-rest bar for ergonomic comfort
The F and Gb triggers were perfectly synchronized, releasing together for smooth, even transitions — a hallmark feature of the Trubore system and one of the reasons many players consider it superior to traditional independent rotor designs.
At retail, a new Trubore independent valve section sold for $3,775 in 2025 (excluding other modular components), making this like-new example an exceptional value at the time of sale.
✦ Why Trubore Valves Stand Out
The Trubore design delivers a consistently open, even response across all registers, eliminating the resistance or “bump” often associated with traditional rotor valves.
This allows bass trombonists to achieve a freer, more resonant sound while maintaining precise control, making it ideal for orchestral, chamber, and solo performance.
