Who the Q30GA Tenor Trombone Is For

The S.E. Shires Q30GA is a professional large bore Bb/F tenor trombone designed for players who need a clear, projecting sound with a broad tonal footprint and an open, usable low register. The QTG gold brass bell with the hand-hammered QI taper and soldered bead supports a tone that stays singing and focused while adding warmth, making it a strong choice for principal and section work as well as solo and chamber settings where clarity matters.

The .547 QW47 handslide in standard-weight yellow brass helps produce breadth without sacrificing definition, and the nickel-silver slide crook contributes to crisp, brilliant articulations. The axial-flow F-attachment is built for an extremely open feel in the low register and a consistent, encompassing tone across the full range, which helps the instrument stay at home in virtually any ensemble.
