The Conn 88HCL SGX is the flagship model in the Conn 88H professional tenor trombone line and represents the very best of Conn’s modern craftsmanship. This instrument is the Christian Lindberg signature model, designed in collaboration with the world-renowned soloist who redefined what was possible on trombone in the classical concert stage.
This example featured a sterling silver bell with gold trim, one of the most desirable configurations available. Sterling silver bells demand more energy from the player but reward with enormous projection and tonal brilliance, especially at loud dynamics where brass bells might lose focus. At the same time, the tone remains gorgeous and colorful at soft dynamics, making it an extremely versatile instrument for orchestral and solo performance.
The 88HCL Lindberg valve is highly regarded as one of the most open, free-blowing, and efficient rotary designs Conn has produced. This example also had an exceptional handslide, described as smooth as silk and perfectly aligned — truly one of the best we have seen at The Brass Exchange.
When new, the Conn 88HCL SGX was priced significantly higher than the standard brass-bell 88H models. In 2025, a new brass-bell 88H sells in the ~$4,700 range, while sterling silver and gold-plate upgrades typically add an additional $2,000 or more. This makes the SGX sterling bell version one of the most premium options in the Conn line.
This particular instrument was in nearly mint condition when sold, with minimal playing wear, original Conn case, and all features in flawless working order.Q&A
Who is Christian Lindberg and why is this model named after him?
Christian Lindberg is a Swedish trombonist, conductor, and composer who is widely considered the most influential classical trombone soloist of the modern era. He transformed the trombone into a recognized solo instrument, inspiring new concertos and advancing performance standards. Conn worked with Lindberg to develop the 88HCL valve and SGX sterling bell model to meet his demanding requirements.
How does a sterling silver bell compare to a brass bell?
Sterling silver bells require more energy to fully resonate but produce a unique brilliance, focus, and power at loud dynamics, unmatched by brass. Brass bells are warmer and more forgiving, blending well in section work. For soloists and advanced orchestral players, the tonal energy of sterling silver can feel incomparable once mastered.
What makes the Conn 88HCL SGX different from other 88H models?
The SGX features a sterling silver bell with gold trim and the Christian Lindberg valve design. These upgrades give it superior projection, tonal flexibility, and valve efficiency compared to standard 88H configurations.
