S.E. Shires Q36YR Bass Trombone Overview
The S.E. Shires Q36YR Q Series professional bass trombone brings Shires bass trombone design into a standardized professional configuration for players who want the company's response, projection, and tonal focus without moving into a fully custom build. The Q36YR is built around an independent F/Gb rotary valve layout, a 9 1/2 inch yellow brass bell, and a .562 inch bass trombone handslide, placing it squarely in the professional bass trombone category for orchestral, wind ensemble, brass ensemble, and commercial low brass work.

- Bell Material: Medium-weight yellow brass
- Valve Configuration: Independent F/Gb rotary valves
- Bore Size: .562 inch

- Serial Number: Q21236
Condition & Setup
This floor model instrument is in excellent playing order and has been professionally serviced, set up, and play-tested. The lacquered yellow brass surfaces present well overall, with glossy bell and body surfaces, bright silver-colored slide and trim components, and only minor fine handling marks visible on some silver-colored tubing near the handgrip and serial area. The bell engraving, dual rotor assembly, handslide, case, mouthpiece, two extra leadpipes, valve oil, slide lubricant, and polish cloth are included.
Who the Q36YR Bass Trombone Is For
The Q36YR is intended for serious bass trombonists who need a professional instrument with a centered low register, clear articulation, and the flexibility of an independent valve system. Its yellow brass bell gives the instrument a balanced tonal core that works well for players who need clarity and presence in large ensembles while still retaining the breadth expected from a modern bass trombone. It is a strong fit for advanced students, university players, professional doublers, and working low brass players who want a well-established Shires Q Series configuration.
Common Questions About the S.E. Shires Q36YR
What distinguishes the Q36YR from a fully custom S.E. Shires bass trombone?
The Q36YR uses a standardized Q Series configuration rather than a fully custom component selection. That gives players a professional Shires design with a clear, consistent setup while keeping the choice process more direct than a custom build.
How does the yellow brass bell affect the playing character?
A yellow brass bass trombone bell is generally chosen for a centered, articulate response with good projection. On the Q36YR, that makes sense for players who need clarity in ensemble texture without giving up the breadth expected from a professional bass trombone.
Why are extra leadpipes useful on a bass trombone?
Interchangeable leadpipes let the player adjust initial response, resistance, and mouthpiece feel. The included extra leadpipes give the player practical room to fine-tune the instrument to their air, embouchure, and musical setting.
