VandorenBass Clarinet Mouthpiece B40
Independent shopping perspective
The Korena take
A bass clarinet mouthpiece with the B40 facing. For bass clarinetists replacing a stock mouthpiece or wanting a defined, consistent facing.
Strong match
Who this is for
- Bass clarinet doublers who need reliable response across the low register
- Replacing the mouthpiece included with a school bass clarinet
- Players who want a wide tip opening with a longer lay
Consider the trade-offs
When to look elsewhere
- Bb soprano clarinet — this will not fit that instrument
- Players who prefer a tighter, more resistant close-tip setup
- Anyone unwilling to re-test reed strengths after switching
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
Bass clarinet size
Physically larger than a soprano clarinet mouthpiece. Takes bass clarinet reeds and a bass-specific ligature.
Detail 03
Wide tip opening
Usually pairs with a softer reed than you would use on a narrower facing. Expect to drop a half strength.
Detail 04
Mouthpiece only
Your neck cork must fit it snugly. Old or compressed cork may need replacing or greasing.
Final check
Know before you order
- 01No reed, ligature, or cap included
- 02Check neck cork fit — too thin and the mouthpiece wobbles, too thick and it will not seat
- 03Plan to re-test reed strengths; the wide tip changes what works
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What reed strength works with a B40?
Wide tip openings generally suit softer reeds. Many players go a half strength below what they use on a narrower facing, then adjust from there.
02Will this fit my Bb clarinet?
No. Bass clarinet mouthpieces are considerably larger and take different reeds. They are not interchangeable with soprano clarinet mouthpieces.
03Do I need a new ligature?
Only if your current one is not a bass clarinet ligature or does not seat evenly on this body. Soprano clarinet ligatures will not fit.
04Why is it more expensive than a soprano clarinet mouthpiece?
More material and a larger, more demanding facing to cut accurately. Bass clarinet mouthpieces sit above soprano equivalents across the board.
