Who the Q36YR Bass Trombone Is For

The S.E. Shires Q36YR is a .562 bore Bb bass trombone with independent F/Gb axial flow valves designed for players who need a clear, projecting sound and an open-feeling low register in professional ensemble settings. Its QII-taper, hand-hammered yellow brass bell is voiced for a clear, singing tone with strong projection and clarity, while still supporting a full, deep low register and broad sound.

The Q62 standard-weight yellow brass handslide helps deliver a broad, colorful response that retains focus, and the nickel-silver handslide crook adds crispness and brilliance to articulations. The independent axial flow valve system is built to keep the sound centered through the valve register and offers flexible valve and slide position choices, making the Q36YR a practical fit for orchestral, wind ensemble, big band, chamber brass, and commercial work.
