1/8
Independent shopping perspective
The Korena take
Bach adapter that lets a French horn mouthpiece with one shank taper seat in a receiver cut for the other. Under $35.
Strong match
Who this is for
- Playing a preferred mouthpiece on a horn with a mismatched receiver
- Doubling on a school horn without swapping mouthpieces
- Keeping a spare in the case for borrowed or rental horns
Consider the trade-offs
When to look elsewhere
- Anyone whose mouthpiece already seats correctly
- Players chasing a tone or response change
- Trumpet, trombone or tuba shanks
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Adds length
Any adapter sits between mouthpiece and leadpipe, so overall length grows slightly. Expect a small pitch and resistance shift.
Detail 03
Bach manufacture
Machined to Bach's own shank dimensions, so it mates predictably with Bach French horn mouthpieces.
Detail 04
French horn only
Sized to horn tapers. Other brass instruments use different shank dimensions and will not seat.
Final check
Know before you order
- 01Confirm which direction you need: your mouthpiece shank versus your horn's receiver.
- 02Adapters can shift intonation slightly; retune after fitting.
- 03Do not force it. A stuck adapter needs a mouthpiece puller, not pliers.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Which way does this adapter convert?
Check your horn's receiver against your mouthpiece shank before ordering. Measure or take both to a tech, since the wrong direction will not seat at all.
02Will it change how my horn plays?
Slightly. Adding an adapter lengthens the gap between mouthpiece and leadpipe, which can nudge intonation and add a little resistance. Most players adjust quickly.
03Can I leave it in the horn permanently?
Yes, but pull it periodically and clean it. Anything left seated in a receiver for months can corrode and seize.
04Does a mouthpiece come with it?
No. This is the adapter alone. You supply the French horn mouthpiece.
