This Kanstul 1662 represents one of the finest American-built bass trombones of its era — a T.I.S. (Tuning in the Slide) design crafted in the spirit of the legendary Conn 62H. Built in Anaheim, California during the company’s final years, this instrument embodies the legacy of Zig Kanstul, who spent over half a century building brass instruments renowned for their quality, precision, and rich sound.
This 1662 features a one-piece gold brass (bronze) bell, paired with a .562 standard bass bore handslide using gold brass outer tubes for added warmth and stability. It came with four removable leadpipes, allowing players to tailor the response. The horn is equipped with Kanstul “Controlled Resistance” rotary valves in a dependent configuration (Bb/F/Gb/D), offering a full set of bass trombone positions including low D in first position with both valves engaged. The T.I.S. design contributes to a centered, focused sound and gives the slide a balanced, resonant feel.
Condition was excellent throughout — the horn showed minimal signs of wear from only 1–2 years of moderate use, and the valves and slide performed flawlessly. It required no additional shop work beyond a standard inspection and setup. The instrument came with a Protec case and four removable leadpipes (mouthpiece not included).
Although Kanstul is no longer in business, instruments like this 1662 remain highly regarded by professional players for their versatility, craftsmanship, and distinctly American character. It would have been an excellent choice for a multi-dimensional professional bass trombonist performing across orchestra, concert band, jazz ensemble, and chamber settings.
