Overview
This Conn 48H Elkhart-era trombone from 1965 SN E75271 is a classic medium-small bore jazz instrument that we’ve seen many times here at The Brass Exchange. We’ve handled dozens of 48H’s over the years, and this one plays exactly as you would expect from a strong Elkhart example—great balance, smooth slide feel, and that unmistakable Conn response.
Key specifications include an 8″ nickel-silver-plated bell with unsoldered bead, a .500 bore gold brass handslide, and nickel-silver end crook. All parts are original with original lacquer.
This horn has received full shop service here, including chemical bath, water key service, and slide adjustment for maximum playability. The handslide has straight inner tubes with only light honest wear and moves easily with modern lubricant.
Player Perspective
The Conn 48H is often called the cousin to the legendary Conn 6H. The playability and response are extremely similar, and many players believe the leadpipe design is essentially the same. The most obvious difference is the nickel-plated bell, which gives a slightly different color and projection.
There are also subtle ergonomic differences. Conn used a heavier-shaped bell brace on the 48H that gives a very comfortable left-hand grip and excellent balance. The right-hand cross brace is slightly smaller in diameter, which many players find very natural.
Both the 48H and 6H use gold brass outer slide tubes. Gold brass can soften some of the higher overtones, similar to using a gold-brass tuning slide on a large tenor with F-attachment, giving a warm, centered sound without losing clarity.
Jazz legend Carl Fontana played a Conn 48H for many years, even recording alongside Frank Rosolino on his Conn 6H—proof of how well these two models pair together.
Today the 48H remains an outstanding vintage jazz and commercial trombone and represents tremendous value compared to new instruments trying to recreate these classic designs.
