Detail 01
27.42mm cup diameter
Very wide. More lip vibrates, so lows open up, but endurance and high-register control cost more effort.

Independent shopping perspective
The Korena take
Large-shank bass trombone mouthpiece with a very wide 27.42mm cup and barrel backbore. Built for advanced players who need low-register definition.
Strong match
Who this is for
- Bass trombonists chasing clean attacks below the staff
- Orchestral and large-ensemble work needing weight down low
- Advanced players with a developed embouchure and air supply
Consider the trade-offs
When to look elsewhere
- Beginners — the wide cup demands air and lip strength
- Small-shank trombones; this will not fit the receiver
- Players who spend most of their time in the upper register
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
Large shank
Fits bass and large-bore tenor trombone receivers. Small-bore horns need a small shank or an adapter.
Detail 03
6.09mm rim width
Narrow rim for this cup size. More flexible and precise on attacks, less cushion over a long session.
Detail 04
7.45mm throat
Open throat. Lets more air through for volume and low-register body, at the cost of some resistance to lean on.
Detail 05
Barrel backbore
Straighter taper than a V-type. Firms up the core of the sound and sharpens attack definition.
Detail 06
Gold plating
Slicker and warmer on the lip than silver. Choose it if silver plating irritates your skin.
Final check
Know before you order
- 01Confirm your horn takes a large shank before ordering
- 02Sold as a mouthpiece only — no case or pouch
- 03Coming from a smaller cup, expect weeks of adjustment before endurance returns
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my tenor trombone?
Only if it is a large-bore tenor with a large-shank receiver. Small-bore tenors need a small-shank piece instead.
02Is the 0AL good for a student?
No. The 27.42mm cup and open throat require developed air support and embouchure. Students should start with something narrower.
03Gold or silver plating — does it change the sound?
The difference is mostly feel. Gold sits slicker and warmer on the lip. Sound is driven by cup, throat, and backbore.
04How does 0AL compare to 1AL?
The 0AL is slightly wider at 27.42mm with a barrel backbore for precise low attacks. The 1AL is 27.11mm with an open backbore and a rounder, darker tone.
