Overview
This Bach 36BLT trombone from the late 1970s represents one of the most flexible medium-bore designs in the Bach lineup. Built with an 8" yellow brass bell, traditional wrap F-attachment rotor, and a .525 bore lightweight nickel silver slide, the instrument offers a balance of clarity, efficiency, and tonal breadth that many players find ideal for varied musical settings.
The instrument arrived in excellent structural condition and had never been damaged or previously repaired. Our shop completed a full professional service including chemical cleaning, rotor maintenance, and complete slide setup. After service the instrument performed extremely well, requiring no additional work to optimize its playing characteristics.
The lightweight LT handslide provides quicker response and slightly easier articulation compared with standard-weight slides, making the 36BLT especially appealing for players who want the flexibility of a medium-bore instrument with a more agile feel.
The trombone includes a protective SKB flight-style case, providing excellent protection for storage and travel.
✦ Historical Perspective
Vincent Bach considered the Model 36 to be one of the most balanced trombone designs he produced. In fact, the later Bach 42B orchestral model borrowed several design elements directly from the 36 series, including aspects of the bell mandrel, valve section layout, and tuning slide configuration.
The primary differences between the two models are bore size and bell diameter. The 36 series uses a .525 bore slide and 8" bell, while the 42 series expands to the larger .547 bore and 8½" bell associated with modern orchestral instruments.
Because of this design lineage, the 36BLT occupies a unique space: it offers greater breadth and projection than small-bore jazz trombones, while still retaining the efficiency and agility that many players miss when moving to larger orchestral horns.
Questions Trombone Players Often Ask
What does the “LT” in Bach 36BLT mean?
The LT designation indicates a lightweight handslide construction. These slides use thinner outer tubes and reduced mass, producing quicker response and a slightly more immediate articulation.
Where does a Bach 36BLT fit compared with larger .547 trombones?
The .525 bore design sits between small-bore jazz instruments and large orchestral trombones. It offers more depth and projection than smaller horns while remaining easier to control and more flexible than full .547 instruments.
Is the Bach 36BLT a good step for advancing players?
Yes. Many teachers recommend the 36 series for players transitioning from student instruments who want a professional-level trombone with an F-attachment but are not yet ready for the size and air requirements of a large-bore orchestral horn.
Do professional players still use the Bach 36 series?
Absolutely. Many professional trombonists keep a medium-bore instrument like the 36BLT for chamber music, contemporary repertoire, commercial work, and situations where a full orchestral trombone may be unnecessarily large.
