Independent shopping perspective
The Korena take

- Intermediate students moving past their first mouthpiece
Consider the trade-offs
When to look elsewhere
- Lead and screamer playing that wants a shallow cup
- Players with silver sensitivity
- Beginners in their first year on trumpet
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
C cup
Bach's medium depth. The all-purpose choice: enough body for concert work without losing the upper register.
Detail 03
Silver plating
Grippier on the lip than gold and durable. Some players react to silver against skin.
Detail 04
Standard Series
Bach's production line rather than hand-finished. Consistent enough that a replacement feels the same.
Detail 05
Trumpet shank
Fits standard Bb and C trumpets. Cornets and flugelhorns take different shanks and will not accept it.
Final check
Know before you order
- 01Mouthpiece only — no pouch, brush or storage case
- 02A wider rim costs endurance for the first few weeks
- 03Do not force a stuck mouthpiece; a shop puller removes it safely
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is a 6C bigger than a 7C?
Yes, slightly wider in rim diameter with the same C cup depth. It gives more room for low notes and a fuller sound.
02Should I move up from a 7C to a 6C?
Only if the 7C feels cramped in the low register. If your range and endurance are fine, there is no need to change.
03Does this fit a cornet or flugelhorn?
No. This is a trumpet shank. Cornets and flugelhorns use different taper sizes and need their own mouthpieces.
04Silver or gold plating?
Silver feels grippier and firmer on the lip. Gold feels smoother and suits players who react to silver. Tone difference is minimal.
