S.E. Shires Q36YR Bass Trombone Overview
The S.E. Shires Q36YR is a Q Series dual-rotor bass trombone built to deliver clear projection, a broad orchestral-style sound, and reliable focus through the full range. Its QYB bell uses a 9 1/2-inch, two-piece, hand-hammered QII taper in yellow brass with a soldered bead for a singing, centered tone and a full, deep low register. A wide .562 handslide in standard-weight yellow brass supports a large, stable sound, while the nickel-silver slide crook adds crispness and brilliance to articulation. The independent F/Gb rotary valve system is designed to keep the valve register comfortable and clear, while giving the player flexible valve and slide-position options.

Who the Q36YR Bass Trombone Is For
The S.E. Shires Q36YR is a professional dual-rotor bass trombone designed for players who need a clear, projecting sound with a broad low register and flexible valve options. It is well suited to orchestral, wind ensemble, brass band, big band, pit, and commercial settings where consistent clarity and centered articulation are required.
What distinguishes the Q36YR within the bass trombone category is the combination of the QYB 9 1/2-inch hand-hammered QII-taper bell for singing projection, the .562 Q62 slide for breadth and stability, and the independent F/Gb rotary valves for position choices and consistent focus throughout the valve register.
Common Questions About The S.E. Shires Q36YR
Is the S.E. Shires Q36YR suitable for professional use?
Yes. The Q36YR is built as a pro-level bass trombone with a hand-hammered Q Series bell, a .562 slide, and independent F/Gb rotary valves intended for demanding ensemble and performance work.
What does an independent F/Gb valve system change compared to a dependent setup?
An independent system allows each valve to be used on its own or together, which expands slide-position choices and can make certain low-register passages and intonation solutions more flexible than a dependent configuration.

It includes the Q Series bass trombone case, a large shank mouthpiece, and a care kit.
