JupiterSousaphone Necks and Tuning Bits Lacquer Mouthpiece Tuning Bit With Screw
Independent shopping perspective
The Korena take
Replacement mouthpiece tuning bit with screw for Jupiter sousaphones. Buy it if yours is dented, stuck, or missing after a repair.
Strong match
Who this is for
- School programs replacing bits lost or damaged during marching season
- Players whose tuning bit no longer holds position under the screw
- Keeping a spare in the case for a marching sousaphone
Consider the trade-offs
When to look elsewhere
- Anyone needing a full neck — this is the bit only
- Non-Jupiter sousaphones, where the receiver taper may not match
- Players wanting a tone upgrade; a tuning bit changes tuning, not sound
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
Lacquer finish
Matches lacquered horn hardware and slows tarnish. Avoid polishes meant for bare brass.
Detail 03
Jupiter-specific fitting
Sized for Jupiter sousaphone receivers. Check your neck taper before ordering if the horn is another brand.
Detail 04
Mouthpiece-end part
Sits between the mouthpiece and the neck, so a bent one causes leaks and a stuffy response.
Final check
Know before you order
- 01No mouthpiece included — this is the tuning bit and screw only
- 02Confirm your model's bit size; Jupiter sousaphones vary across generations
- 03Grease the fitting lightly so it seats without scratching
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does this come with a mouthpiece?
No. It is the tuning bit and its screw. Your existing mouthpiece seats into it.
02Will it fit a non-Jupiter sousaphone?
It is made for Jupiter sousaphone necks. Other brands use different receiver tapers, so measure before ordering.
03What does the screw do?
It clamps the bit at a chosen depth so your tuning position holds instead of creeping while you play.
04Is this the whole neck?
No. It is only the tuning bit at the mouthpiece end. A full neck is a separate part.
