Conn 48H Jazz Trombone, made in the 1970s, stamped “Connstellation,” manufactured in Abilene, Texas, SN GK970195. This .500 bore trombone features an 8" yellow brass bell and is one of Conn’s most well-known small bore jazz models from the post-Elkhart era.
This example has had full shop service, including a chemical bath and precision slide setup. We also re-lacquered the tuning slide to improve appearance while keeping the rest of the lacquer original. Aside from this cosmetic touch-up, all parts remain original and well preserved.
The handslide is excellent, with no plating loss on the inner tubes and perfectly straight alignment. There is one small ding on the endcrook, which we chose not to repair because the slide action is exceptionally smooth—and we didn’t want to risk compromising the feel. The horn plays very well as is.
Includes a non-original hard case that is compact, lightweight, and ideal for a student commuting across campus or anyone needing a highly portable setup.
Q: How does the 48H compare to the 6H for jazz use?
A: Both models are excellent small bore jazz trombones, but the 48H tends to play a little darker due to its nickel silver bell, whereas the 6H features a standard yellow brass bell for a brighter tone. Many players appreciate the 48H for its warmth and versatility in lead or solo roles.
This Conn 48H has been sold and is now displayed here for reference by Conn fans and jazz trombone collectors.
