Overview
This S.E. Shires Tenor Trubore valve section is offered here as a pre-owned modular Shires component and has been fully serviced and inspected in our shop.
Estimated to be approximately 8–10 years old, the section has undergone a complete chemical cleaning, mechanical inspection, and play test to confirm proper performance. The valve linkage operates smoothly, rotor and casing tolerances are correct, and the section plays exactly as it should.
Cosmetically the lacquer shows minor wear consistent with normal professional use, but structurally the component remains excellent and installs properly with Shires Custom Series bell sections and handslides.
This valve section is now offered as TBE Shop-Certified and player ready.
Understanding the Shires Trubore Valve System
The Shires Trubore valve system is one of the most respected rotor designs used in modern trombone construction.
Unlike traditional rotor valves that narrow through the center of the valve core, the Trubore design maintains a larger continuous bore profile through the valve, reducing airflow restriction when the valve is engaged.
Key design characteristics include:
• Large bore-through rotor geometry for improved airflow
• Balanced resistance between open and valve registers
• Clear articulation when using the F attachment
• Consistent response across dynamic ranges
Many professional players appreciate how the Trubore system allows the instrument to maintain the natural feel of the open horn even when the valve is engaged.
🎧 Player Perspective
For Shires players building or refining a modular tenor trombone, the Trubore valve section offers a particularly open and responsive feel.
Compared with older traditional rotor designs, the Trubore system tends to feel:
• More open when using the valve
• Better balanced between open and F-attachment registers
• Responsive across orchestral, symphonic band, and commercial settings such as pit orchestras or anywhere a large bore tenor is used.
Players who prefer the modern Shires orchestral-style response often seek out Trubore-equipped valve sections for their modular builds.
