This Conn 4B bass trumpet from the 1960’s Elkhart, Indiana era is a true rarity in the world of vintage brass instruments. The bass trumpet occupies a unique space in the brass family — pitched lower than a standard trumpet, with a tonal weight that appeals to trumpet players, trombone players, and euphonium players alike. While some Conn 4B models were likely intended for marching use, their bold, resonant voice has always been most at home in orchestral and studio work, where a distinctive brass color is needed.
This particular example received complete professional shop service, including a chemical bath, fresh pads and felts, and thorough valve work. The compression is excellent with no leaks, and the instrument was personally play-tested. A Bach 7C small shank trombone mouthpiece proved a perfect match, producing a sound that was full, warm, and surprisingly agile for a bass trumpet. Although not common in jazz, the 4B’s tonal palette could easily inspire adventurous improvisers or crossover projects.
Mechanically and cosmetically, it represents one of the best vintage bass trumpet examples we’ve encountered. Conn’s Elkhart-era craftsmanship is evident in its response and intonation, and collectors value this period for both playability and build quality. Includes the original case; mouthpiece not included.
This instrument has been sold and now appears in our archive as a historical reference for musicians, collectors, and anyone researching rare Conn brass instruments.
