Independent shopping perspective
The Korena take
Small-shank trombone mouthpiece with a wide 25.90mm cup and open 7.13mm throat. For developed players who want large-bore weight from a small-bore horn.
Strong match
Who this is for
- Small-bore tenor players who want more body and volume
- Doublers stepping down from a large-bore horn wanting familiar dimensions
- Section playing where a stock small-shank piece sounds thin
Consider the trade-offs
When to look elsewhere
- Large-shank receivers — the shank won't seat
- Developing embouchures; the wide cup drains endurance quickly
- Lead work wanting a bright, shallow, easy top end
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
25.90mm cup diameter
Wide for a small-shank piece. More lip vibrates, so lows fill out and the top costs more work.
Detail 03
6.77mm rim width
A wide rim spreads pressure over more lip. More comfort on long sessions, slightly less agility between partials.
Detail 04
7.13mm throat
Open for a small shank. Less resistance, more air required, and a bigger sound before the tone breaks up.
Detail 05
Medium backbore
Sits between a bright V taper and a dark barrel. Keeps the core even rather than pushing the sound one direction.
Final check
Know before you order
- 01Measure your receiver — small shank only, and no adapter is included
- 02Mouthpiece only. No pouch or case
- 03The bigger cup and throat need more air; expect an adjustment period
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit a large bore trombone?
No, it's small shank. The 4BL is the large-shank equivalent with the same 25.90mm cup, 6.77mm rim, 7.13mm throat and medium backbore.
02How does 4BS compare to 5BS?
The 4BS is bigger throughout: 25.90mm cup against 25.73mm, wider rim, and a 7.13mm throat against 6.87mm. Fuller and more open, but more demanding.
03Is this a good step up from a student mouthpiece?
Only once your embouchure is developed. The large cup on a small bore is aimed at players who already have the air and stamina to drive it.
04Why put a large cup on a small bore trombone?
To get big-bore weight and low-register depth without changing horns. The trade is more air needed and a harder upper register.
