Overview
The Conn 48H Connstellation from 1958 is one of the most distinctive small bore trombones produced during the Elkhart era—a period widely regarded as Conn’s most innovative and consistent.
This example stood out as one of the finest we’ve handled. It retained exceptional original condition, with clean lacquer throughout and a handslide that was straight, responsive, and performing at a high level.
With its .500 bore and unique bell construction, the 48H offers a different playing experience compared to more common small bore models like the 6H—making it especially appealing to players seeking something with character and individuality.
Player Perspective
From a playing standpoint, the Conn 48H delivers a focused, compact sound with added warmth and color, setting it apart from more traditional yellow brass small bore instruments.
- The response is immediate and efficient
- The tone has a slightly darker core compared to a Conn 6H
- The instrument offers excellent clarity for jazz and commercial playing
For players who enjoy the feel of a 6H but want something with a bit more tonal depth and personality, the 48H is a compelling option.
Design and Characteristics
- .500 bore small tenor trombone
- 8" unsoldered rim nickel-plated bell
- Bell constructed from a higher copper-content brass alloy beneath plating
- Gold brass handslide with unique bracing and curved corners
- Elkhart, Indiana production (pre-1970)
Conn’s design approach during this era emphasized experimentation and innovation, and the 48H reflects that mindset. The unsoldered rim bell and specialized alloy contribute to the instrument’s distinctive tonal profile and response.

Historical and Model Context
Conn’s Elkhart-era instruments (pre-1970) are widely regarded as some of the most musically expressive brass instruments ever produced.
During this period, Conn focused on:
- hand-fitted construction
- unique bell designs and alloys
- innovative engineering approaches
Models such as the 6H, 8H, 88H, and 62H became industry benchmarks, while more specialized designs like the 48H offered players alternative tonal options.
One of the defining characteristics of these instruments is that no two examples play exactly alike, giving each horn a unique personality that many players continue to seek out today.

Questions Trombone Players Often Ask
How does the Conn 48H compare to a Conn 6H?
While the Conn 48H shares a similar .500 bore with the more common 6H, the bell construction—especially on 1950s examples—sets it apart in a meaningful way.
The 48H Connstellation bell from this era is nickel-plated, but not made of solid nickel silver. Under the plating, the alloy is widely believed to be a higher copper-content brass, sometimes associated with Conn’s “Coprion”-style concept. This is important because copper-rich alloys tend to produce a darker, broader tonal character compared to standard yellow brass.
In practical terms:
- The 48H often plays darker and more complex than a typical 6H
- The sound has less high-frequency edge, with a smoother, more centered core
- It can feel closer in concept—on a smaller scale—to models like the Conn 88H, where higher copper content contributes to a broader symphonic sound
By contrast, later Connstellation models (particularly into the 1960s) are generally believed to use more yellow brass-based alloys under the plating, which results in a slightly brighter and more direct response.
This is one of the reasons players and collectors often seek out 1950s-era 48H models specifically—the combination of design and materials gives them a tonal character that is noticeably different from both the 6H and later production Connstellations.
What makes Elkhart-era Conn trombones special?
Elkhart-era instruments are known for their craftsmanship, material quality, and distinctive playing characteristics. Many players feel these instruments offer more individuality and tonal complexity than later production models.
Is the Conn 48H a good jazz trombone?
Yes. Its .500 bore, quick response, and focused sound make it well suited for jazz, commercial, and small ensemble playing.
