Detail 01
Large shank
Fits large-bore receivers only. Check your leadpipe before ordering; a small-shank horn needs the small-shank version.

Independent shopping perspective
The Korena take
Large-shank trombone mouthpiece, 5BL, with a medium-deep cup and medium backbore. For advanced and principal players on large-bore horns.
Strong match
Who this is for
- Large-bore tenor trombone with a large-shank receiver
- Section leads who need a flexible high range
- Players wanting more cup depth than a shallow lead piece
Consider the trade-offs
When to look elsewhere
- Small-shank horns — it will not seat properly
- Beginners, who are usually better served by a standard size
- Players with a silver allergy or plating sensitivity
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
25.73mm cup diameter
Mid-size rim. Enough surface for endurance without the wide feel of a 4 or 1 size.
Detail 03
6.64mm rim width
A moderately wide rim contact. Spreads pressure over the lip rather than concentrating it.
Detail 04
6.87mm throat
Narrower than the barrel-backbore 5AL. More resistance, which gives you something to push against up high.
Detail 05
Medium backbore
Sits between free-blowing and tight. Balances the medium-deep cup rather than opening it further.
Detail 06
Silver finish
Slicker and cooler on the lip than gold plate; some players react to the plating.
Final check
Know before you order
- 01Mouthpiece only — no case, pouch, or brush included
- 02Confirm large versus small shank; the two are not interchangeable
- 03Give any new mouthpiece a couple of weeks before judging it
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What is the difference between the 5BL and the 5AL?
Same 25.73mm cup diameter and rim width. The 5AL has a wider 7.30mm throat with a barrel backbore; the 5BL is 6.87mm with a medium backbore.
02Will this fit my trombone?
Only if it has a large-shank receiver, typical of large-bore tenor and bass trombones. Small-shank horns need a small-shank mouthpiece.
03Is this good for high playing?
The medium-deep cup and 6.87mm throat are set up for a flexible high range while keeping body in the sound.
04Does it come with a case?
No, it ships as the mouthpiece alone.
