Overview
This Bach 36 medium bore tenor trombone SN 21624 was built in the mid-1970s during the Bach Corporation Era, a period widely respected for production consistency, stable build quality, and dependable playing characteristics. Featuring the classic 8" yellow brass bell and standard-weight .525 bore handslide, the Bach 36 occupies one of the most useful size categories in the modern professional landscape.
For many orchestral players, this model functions as a secondary orchestral horn — a straight tenor that complements a primary .547 bore trigger instrument. It is especially valued in modern programming and film score work, where clarity, efficiency, and tonal flexibility are often more important than maximum mass or breadth. This size allows players to move easily between contemporary orchestral literature, studio sessions, chamber settings, and crossover repertoire without compromise.
Player Perspective
Among orchestral and studio professionals, the Bach 36 has become a quiet essential. The .525 bore provides noticeably more core and projection than a small jazz tenor while remaining more agile and compact than a full .547 bore F-attachment horn when a trigger is unnecessary.
This particular instrument responds immediately and speaks cleanly across the range, making it especially effective for modern orchestral writing and film scores that demand fast articulation, clean attacks, and precise dynamic control. It is the type of horn many professionals keep on the stand for sessions and rehearsals where efficiency and adaptability matter.
A custom, one-of-a-kind balance weight has been fitted, improving overall ergonomics and helping the instrument sit naturally during long rehearsals, pit work, or recording sessions — a meaningful refinement for real-world professional use.
Condition & Service
This was clearly a professional player’s instrument and has never had damage or repair work. Most of the original lacquer is missing, which is common for Bach trombones of this era. In the 1970s and 1980s, many players intentionally removed lacquer to enhance resonance and response.
The trombone has completed full professional shop service here at The Brass Exchange, including a chemical bath and full mechanical evaluation.
It is fully player-ready and performs exactly as it should — no excuses, no deferred work.
The original Bach case is included. The case is structurally sound; the main handle strap needs replacement. All hardware is intact, and this is a simple DIY fix.
Value & Context
A new Bach 36 tenor trombone now carries a 2026 retail price of $3,729. This Corporation Era example delivers the same core design, dimensions, and musical utility that professional players rely on — at a significantly lower entry point, with the added benefit of a fully stabilized instrument that has already proven itself in professional use.
For orchestral and film players seeking a dedicated straight tenor to complement a .547 bore trigger horn, this represents exceptional value.
Questions Trombone Players Often Ask
Why do orchestral players keep a straight tenor like the Bach 36?
Many professionals use a straight tenor for modern orchestral works, film scores, and mixed programming where clarity, speed, and balance are prioritized over maximum tonal weight.
Is a .525 bore large enough for orchestral use?
Yes. While not a replacement for a large-bore trigger horn, the .525 bore offers excellent projection and blend in many contemporary settings and is often preferred for specific repertoire.
Does lacquer removal affect performance?
Many players believe lacquer removal increases resonance and immediacy of response. This was a common and intentional practice during the era this instrument was played professionally.
