Condition & Setup

Refurbished trombone with few signs of use. We purchased this instrument directly from the manufacturer and it has seen only extremely light use as a demo or display model. It has been professionally serviced in our shop, set up to spec, and play-tested to confirm proper slide action, valve function, and response.

Who the Q36YA Bass Trombone Is For

The S.E. Shires Q36YA is a professional Bb bass trombone with independent F and Gb axial flow valves designed for players who need a clear, projecting sound with a full low register and a flexible valve setup. Its QII-taper yellow brass bell supports a centered, singing tone and broad sound, while the .562-inch Q62 handslide preserves clarity, color, and projection across dynamic ranges.

This model is well-suited to orchestral bass trombone parts, wind ensemble and brass band literature, and commercial settings where articulation clarity and valve-register openness matter. The independent axial flow valve system helps retain focus throughout the instrument’s range and allows more choices for alternate positions and efficient slide movement, particularly in technically dense or low-register passages.

Common Questions About The S.E. Shires Q36YA

What does “independent F and Gb axial flow valves” mean in practical terms?

It means the instrument has two valves that can be used separately or together, typically providing Bb, F, Gb, and combined valve tubing options for alternate positions and intonation solutions. Axial flow valves are designed to feel more open than traditional rotary valves, helping keep the valve register responsive and less resistant.

Is the Q36YA suitable for professional orchestral bass trombone work?

Yes. The Q36YA’s .562-inch bore slide, 9 1/2-inch QII-taper bell, and independent valves support the projection, clarity, and low-register breadth expected for professional bass trombone playing in orchestral and large-ensemble settings.

What is included with this instrument?

This Q36YA includes the Shires Q Series bass trombone case, a Shires 1.25MD large shank mouthpiece, a care kit, and three interchangeable yellow brass leadpipes.
