27.11mm cup diameter
One of the widest in this range. More lip inside the cup means bigger low register but faster fatigue.

Independent shopping perspective
The Korena take
Large-shank trombone mouthpiece with a 27.11mm cup and open backbore. For tenor and bass trombone players wanting a big, free-blowing sound.
Strong match
Who this is for
- Large-bore tenor or bass trombone players needing a wide rim
- Players who want less resistance and a freer air stream
- Anyone moving up from a smaller cup for more low end
Consider the trade-offs
When to look elsewhere
- Small-shank horns — the large shank will not seat
- Lead and commercial players wanting a compact, bright sound
- Players with limited air support; the open blow eats air
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 large-bore tenor and bass trombone receivers only. Small-bore horns need the small-shank version.
Detail 03
Open backbore
Less resistance behind the throat. The horn blows freer and opens up at volume, but takes more air.
Detail 04
7.45mm throat
Wide throat passes more air than the 6.66mm sizes, favoring volume and low-register body over pinpoint articulation.
Detail 05
6.09mm rim width
Narrow rim for this cup size. More flexibility and slur control, less cushion on long sessions.
Detail 06
Silver plating
Slightly grippier feel than gold and a firmer response. Some players react to silver against the skin.
Final check
Know before you order
- 01Check your receiver — large shank only, and it will not adapt down
- 02Mouthpiece only; no pouch, case, or brush included
- 03Give your embouchure a few weeks before judging a rim change
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my trombone?
Only if your horn has a large-shank receiver, which is typical of large-bore tenors and bass trombones. Small-bore tenors take a small shank and will not accept it.
02Is 1AL good for bass trombone?
Yes. The 27.11mm cup and 7.45mm throat suit bass trombone, and the open backbore supports the low register with a free blow.
03How is this different from the 4AL?
The 4AL is a 26mm cup with a barrel backbore and a wider 6.72mm rim. The 1AL is wider in the cup, narrower on the rim, and blows more openly.
04Silver or gold plating — does it matter?
Silver feels grippier and a touch firmer on the lip. Gold feels smoother and slicker. Players with a silver sensitivity should choose gold.
