Who the STBQ36GR Bass Trombone Is For

The S.E. Shires STBQ36GR is a professional dual-rotor bass trombone designed for players who need a broad, deep low register with clear projection and reliable response across all registers. The QGB gold brass bell’s hand-hammered QII taper supports a clear, singing core with strong projection, while the .562 Q62 handslide helps deliver a wide sound that maintains color and definition.

This model is well suited to orchestral bass trombone work, wind ensemble, brass band, commercial playing, and pit work where flexibility matters. Its independent F and Gb rotary valves help retain focus in the valve register and provide more options for slide positions and alternate fingerings, and the nickel-silver slide crook adds crispness and brilliance to articulation. The included set of three interchangeable leadpipes lets experienced players fine-tune response and feel for different repertoire and halls.

Common Questions About The S.E. Shires STBQ36GR

What makes the STBQ36GR different from a dependent-valve bass trombone?

The STBQ36GR uses independent F and Gb rotary valves, which allows either valve to be used alone or together. This gives more flexibility in valve combinations and slide positions compared with dependent systems, and it helps players manage intonation and facility in technical passages.

Is the S.E. Shires STBQ36GR suitable for professional orchestral playing?

Yes. The .562 bore, 9 1/2-inch gold brass QGB bell, and independent rotary valves are professional-application specifications intended to provide projection, clarity, and a full low register required for orchestral and large-ensemble bass trombone parts.

What is included with the STBQ36GR?

It includes the S.E. Shires Q Series bass trombone case, a mouthpiece, and a care kit, plus three interchangeable yellow brass leadpipes.
