The Bach 36B remains one of the most trusted medium-bore (.525) tenor trombones for advancing students and professional players who want a horn that bridges the gap between smaller jazz models and larger orchestral tenors.
With its agile response and full-bodied tone, it has long been a go-to choice for solo, chamber, and pit-orchestra work.
This particular 36B was built in the mid-1980s (serial no. 83623) and came to The Brass Exchange as a single-owner instrument.
It had been well-cared-for over the decades and retained its classic Bach character.
We performed a complete shop service, including a chemical bath, rotor valve check, and professional slide alignment.
The slide end-crook had significant lacquer wear, so it was removed, carefully buffed, re-lacquered, and re-set for improved alignment.
The result is a smooth, responsive slide that performs exactly as a good Bach 36B should.
The bell section has never been damaged, and its original lacquer is in excellent condition.
The 8″ yellow-brass bell offers that warm, centered Bach sound with good projection, while the .525-bore slide paired with the traditional F-attachment makes it a versatile horn for many performance settings.
It accepts a standard small-shank mouthpiece such as a Bach 6 ½AL or 5G, giving players plenty of options to fine-tune their sound.
The horn also retains its original case, still in great condition.
This Bach 36B has been sold and now appears here in our Historical Archive as a reference for players, educators, and collectors who want to understand the enduring appeal of the Bach 36-series.
Q: Why do many players choose the Bach 36B over the larger 42B?
A: The 36B’s medium-bore design responds more easily and offers a slightly brighter, more compact tone — ideal for lighter orchestral, pit, or solo work.
Q: How important is professional slide service for a pre-owned Bach?
A: Extremely important — a smooth, well-aligned slide improves response, intonation, and player comfort while maintaining the horn’s long-term value.
Q: Does the 36B use a standard small-shank mouthpiece?
A: Yes. It’s compatible with popular small-shank sizes such as Bach 6 ½AL or 5G.
Q: Is a mid-1980s Bach 36B still competitive with newer models?
A: Absolutely. Instruments from this period are known for solid build quality and remain popular among players who want classic Bach tone and feel.
