Crafted during the highly regarded Corporation Era of the 1970s, this Bach 12 trombone bears serial number 36788 and represents the sweet spot of vintage small bore jazz horns. With a 7.5" yellow brass bell and a .500 bore standard weight handslide, it offers the tight, responsive feel favored by lead players seeking both control and brilliance. This model is famously associated with trombonist Bob McChesney, who recorded extensively on a Bach 12 for its clarity, projection, and nimbleness in upper registers.
This instrument was a single-owner horn and remains in excellent playing condition. It has received full professional shop service including a chemical bath and precise handslide alignment. The crook was removed to correct minor dings, then carefully reset. It remains unlacquered for visual clarity, while the rest of the horn retains its original lacquer in very good condition. There are no mechanical or tonal issues—this is a straight, gig-ready horn.
Players seeking a high-quality small bore jazz or lead trombone will appreciate the effortless response and core sound of this vintage Bach. It plays evenly across the range and would suit any advancing musician, college student, or pro doubling on small bore.
Includes the original Bach case from the era, still functional and protective.
Why do many pro players prefer the .500 bore size for jazz?
The .500 bore offers an ideal balance of control, brightness, and agility—perfect for lead and jazz settings. It projects clearly without sounding overly edgy and responds easily to nuanced articulation. For many players, it’s the most versatile size for small ensemble or commercial work.
❓ Questions Trombone Players Often Ask
Why do players value Corporation Era Bach trombones so highly?
In the 1970s Bach maintained tight manufacturing standards, resulting in highly consistent bells, slides, and hand-fit components. Many pros feel Corporation Era horns have a livelier core and more colorful resonance than later production periods.
Is the Bach 12 a good lead trombone for advancing players?
Yes. The .500 bore and 7.5" bell give the Bach 12 a brilliant, focused sound that slots easily and supports upper-register clarity. It’s a strong step-up horn for college jazz majors and working commercial players.
How does a vintage .500 bore compare to modern small-bore designs?
Older Bach .500 slides often feel more flexible and vibrant than many modern horns. They provide quick response and an easy blow without sacrificing stability — a reason the Bach 12 remains a favorite among players who want an agile, colorful jazz voice.
