The Conn 78H Trombone, built in 1951 during the Elkhart Era, stands as one of Conn’s most refined professional medium-bore models. With proportions close to a Bach 36, the 78H offered a unique balance of projection, warmth, and flexibility, making it a favorite for versatile players who needed a horn capable of both symphonic depth and jazz agility.
This example was a single-owner instrument, kept in remarkable condition for over seven decades. It retained all original parts and lacquer, with no history of replacement or modification. The horn was freshly chemically cleaned and fully serviced before listing, ensuring excellent playability for its next performer.
The 8" yellow brass bell featured an unsoldered rim, producing a colorful and responsive tone. Its .522 bore handslide was in very good condition, with inner tubes described as nearly perfect. The slide’s responsiveness contributed to the horn’s flexibility — agile enough for jazz players accustomed to a Conn 6H, but with greater depth and breadth when pushed.
Many musicians consider the 78H an ideal “artist’s horn,” the type of instrument that a professional could develop a signature sound around. It retained Conn’s unmistakable tonal character but held together beautifully at higher volumes and broader dynamic ranges. At The Brass Exchange, this was noted as the finest 78H we had ever seen, a true standout among Elkhart-era examples.
