S.E. Shires Q39GR Contrabass Trombone Overview
The S.E. Shires Model Q39GR Q-Series Contrabass Trombone is a modern, American-tuned contrabass trombone designed to deliver breadth, clarity, and responsive control across the full register. Built around an independent F/C/Db/A valve system with Rotax rotary valves, the Q39GR offers stable intonation and fluid transitions while keeping the valve layout familiar to bass trombonists. A .590 inch bore and a 10.5 inch two-piece gold brass detachable-flare bell support a broad, resonant sound with depth and presence, finished in clear lacquer and supplied with a factory S.E. Shires case, mouthpiece, and care kit.

Who the Q39GR Contrabass Trombone Is For
The Q39GR contrabass trombone is an American-tuned, independent-valve contrabass trombone built for players who need a powerful low-brass voice with clear response and secure control. Because its F/C/Db/A configuration parallels common bass trombone valve layouts, many scale patterns and technical habits transfer directly from bass trombone, helping experienced bass trombonists adapt quickly while encouraging an effective balance between valve use and extended-position slide technique.
This model is well-suited for orchestral and large-ensemble work where projection and stability are required, and it also supports solo and chamber playing where clarity and clean transitions matter. The .590 inch bore and 10.5 inch detachable-flare yellow brass bell are designed to provide a broad, resonant core sound with depth and color while retaining the refinement and characteristic response associated with S.E. Shires instruments.
