Overview
The Kanstul 1588 is a professional-level large bore tenor trombone built for players who want the familiar breadth and stability of a classic 88H-style instrument, paired with modern American craftsmanship and a distinctly warm tonal core. Featuring a .547 bore, open-wrap F-attachment, and an 8.5" bronze (gold brass) bell, this trombone delivers depth, clarity, and effortless response across the full range.
If you’re comfortable on instruments like the Conn 88H or Bach 42, the 1588 will feel immediately familiar — but with added warmth, smooth airflow through the valve section, and a refined, confident playing feel that stays consistent in demanding repertoire.
Player Perspective
This is a horn that stays centered and calm under pressure. The bronze bell adds richness and color without sacrificing clarity, giving the sound a broader cushion that blends beautifully in orchestral and symphonic settings. Articulation remains clean, and the horn opens naturally when pushed, making it equally comfortable for lyrical passages and full-ensemble playing.
The open-wrap F-attachment contributes to an even, free-blowing feel in the trigger register, particularly for players who spend time below low F. Airflow feels smooth and continuous, with no sense of congestion, while slotting remains secure and predictable. The result is a horn that feels stable, cooperative, and confidence-inspiring.
Setup & Playing Feel
The handslide has received a professional in-house setup and is exceptionally smooth — the kind of slide that disappears under the hand and lets the player focus entirely on music. Valve action is fast and quiet, suitable for orchestral, studio, and solo use. One removable leadpipe is included, allowing subtle tailoring of response to the player’s preference.
Condition Summary
This is a single-owner instrument in super-mint condition. It arrived exceptionally clean and unchanged, requiring no repairs. After a full inspection and play test, no issues were found. The trombone presents beautifully and plays exactly as a professional-level instrument should.

Questions Trombone Players Often Ask
Why choose a bronze bell on a large bore tenor?
Bronze (gold brass) bells add warmth, depth, and complexity to the sound while maintaining projection. They’re especially appealing to players who want a rich tonal core that blends easily without becoming dull or unfocused.
Does the open wrap really make a difference?
For players who frequently use the F-attachment, yes. An open wrap can reduce resistance and smooth airflow in the valve register, making lower passages feel more even and less effortful while preserving secure slotting.
Who is this trombone best suited for?
The Kanstul 1588 is an excellent choice for advancing students, college players, educators, and professionals seeking a first or primary large bore F-attachment trombone with true professional performance and long-term durability.
Rarity & Context
When available new, the Kanstul 1588 sold for over $4,000. With Kanstul no longer in production, clean examples in super-mint condition — especially with bronze bells and professional slide setup — are becoming increasingly difficult to find.
