The Kanstul 1555 Small Bore Jazz/Commercial Trombone represents the high-quality American brass craftsmanship that Kanstul maintained until closing in 2019.
This archived example was a lightly used, like-new instrument, showing virtually no signs of wear or prior service needs.
Key features included a 7.5-inch yellow-brass bell paired with a .500 bore lightweight handslide — a classic small-bore configuration favored by jazz and commercial players for its agile response, crisp articulation, and vibrant projection.
The slide came equipped with three removable leadpipes, allowing players to fine-tune resistance and response to personal preference.
One standout design detail was the curved comfort grip on the handslide brace, reminiscent of the celebrated Earl Williams Los Angeles–era models, which many players find more natural for the left-hand hold.
The slide action was described as superb — smooth, quick, and tension-free, delivering an excellent feel for both lead and section work.
The horn came with its original Kanstul mouthpiece and protective case, making it a complete package for any advancing student or professional jazz player seeking a responsive, top-tier small-bore tenor.
When it was last available new, the Kanstul 1555 retailed at over $2,200 and often required an 8-week special order wait time.
Having one in near-new condition and ready for immediate delivery was a rare opportunity.
Although this instrument has been sold, it now appears here in our Archive of Sold Instruments as a reference for musicians, collectors, and researchers interested in the history and enduring appeal of Kanstul small-bore jazz/commercial trombones.
FAQ
What makes the Kanstul 1555 stand out among small-bore jazz trombones?
Its combination of agile .500 bore response, a slightly larger 7.5" bell for fuller projection, and the curved comfort grip design gives it a modern yet classic feel — great for lead, combo, and commercial settings.
How does the Kanstul 1555 compare to vintage Earl Williams or King 2B models?
It delivers a similar nimble, singing upper register and lively character but benefits from modern precision machining, removable leadpipes, and Kanstul’s attention to clean airflow.
Is the Kanstul 1555 still sought after today?
Yes. Since Kanstul’s closure in 2019, their professional jazz and commercial models have become harder to find in top condition, making them a desirable choice for players who want reliable American-made small-bore horns.
