Overview
This Kanstul 1588 Open Wrap Tenor Trombone represented an uncommon professional configuration combining an 8.5" bell, open-wrap F-attachment, Kanstul Controlled Resistance rotary valve, and an approximately .530"/.547" dual-bore handslide with a fixed small-shank leadpipe.
The result was a trombone with much of the breadth and projection associated with a traditional large-bore tenor, but with a more compact and responsive feel. It occupied an interesting middle ground for players seeking more tonal authority than a typical medium-bore trombone without the feel of a conventional straight .547" setup.
Players who enjoy instruments such as the Bach 36B but occasionally want a broader sound may find this Kanstul configuration especially appealing. It may also suit players who appreciate the sound of a Bach 42B or Conn 88H but prefer a slightly more agile and efficient response.
Kanstul’s final published price list from 2019 showed an MSRP of approximately $4,000 for the Model 1588. With Kanstul no longer producing instruments, clean examples of its professional trombones have become increasingly difficult to find.
This instrument has been sold and is presented here as part of The Brass Exchange Archive.

Player Perspective
The approximately .530"/.547" dual-bore handslide gave this instrument a more compact response than a traditional straight .547" tenor while retaining the breadth and presence of an 8.5" bell. Articulation was clean and immediate, and the trombone responded quickly without becoming excessively bright or lightweight in character.
The fixed leadpipe accepted standard small-shank tenor trombone mouthpieces. This created a familiar transition for players coming from medium-bore or medium-large-bore instruments while providing access to a broader tonal palette.
The open-wrap F-attachment and Kanstul Controlled Resistance rotary valve provided consistent airflow through the trigger register. Overall, this trombone delivered much of the authority of a large tenor while feeling slightly more compact and efficient in the hands.
