The Conn 88HCL SGX Christian Lindberg model represents the pinnacle of the Conn 88H line. Built with a sterling silver bell and gold trim, this premium example came to us in immaculate adult-owned condition with no history of damage, repair, or plating work. The original silver and gold finishes remained fully intact, exemplifying the exceptional craftsmanship associated with the SGX series.
At the heart of this model is the Christian Lindberg valve — a collaboration between Conn and world-renowned soloist Christian Lindberg. The valve offers a short throw, fast return, and extremely open feel, providing players with superior response and agility. The handslide on this instrument was equally impressive: fast, smooth, and highly reliable, reflecting the care and maintenance of its previous professional owner.
The SGX has earned a global reputation for its brilliant projection, orchestral presence, and tonal flexibility. Whether performing solo literature or leading a section, this configuration delivers the clarity, color, and dynamic range associated with Lindberg’s signature sound.
With standard brass-bell Conn 88H models retailing around $4,700 (2025 pricing), and sterling silver + gold trim upgrades adding $2,000+, the SGX stands among Conn’s most desirable and premium offerings.
This example included the original case and both standard-weight and heavy valve caps. Mouthpiece not included.
🤔 Q&A
What makes the Conn 88HCL SGX different from the standard 88H?
The SGX includes a sterling silver bell with gold trim and the Christian Lindberg valve, both of which provide superior projection, tonal brilliance, and a more efficient blow compared to standard 88H setups.
How does the Lindberg valve improve performance?
Its shorter throw and smooth mechanical feel allow for cleaner, faster transitions, enhanced airflow, and improved clarity across all registers.
Why choose a sterling silver bell?
Sterling bells require more energy to drive, but once fully resonating, they deliver unmatched tonal power, dynamic reach, and brilliance — characteristics prized in solo and orchestral performance.
