Independent shopping perspective
The Korena take
A tuba mouthpiece in Yamaha's Standard line, sized like a Bach 25 but with a narrower rim. Suited to students and doublers wanting a smaller feel.
Strong match
Who this is for
- Players who find a Bach 25 rim slightly too wide
- Students on BBb tuba needing a manageable rim size
- Doublers wanting a consistent backup to a Bach 25
Consider the trade-offs
When to look elsewhere
- Players wanting a large-bore orchestral sound from a Helleburg-size cup
- F tuba specialists needing a shallower cup
- Anyone already comfortable on a wider rim

Final check

- 03Rim size changes are felt within days, not minutes, expect an adjustment period
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How is the 64 different from the 65?
The 65 matches Bach 25 dimensions. The 64 is the same idea with a smaller rim diameter, so it feels tighter on the lips.
02Will this fit my sousaphone?
It fits instruments taking a standard tuba shank. Check what your sousaphone receiver accepts before ordering.
03Is this a good step up from a stock mouthpiece?
It is a standard-line piece rather than a professional model. It is a sensible replacement or spare, not a large upgrade.
04Which size should I get for F tuba?
The 67B4 in this line follows a Miraphone C3 with a shallower cup, which is described for F tubas. The 64 is not.
