VandorenBass Clarinet Mouthpiece B45
Independent shopping perspective
The Korena take
Vandoren's B45 bass clarinet mouthpiece — a widely used step up from stock mouthpieces for students and working players alike.
Strong match
Who this is for
- Replacing the stock mouthpiece that came with a student bass clarinet
- Concert band and orchestral bass clarinet parts
- Players wanting a bigger, fuller low register
Consider the trade-offs
When to look elsewhere
- Soprano Bb clarinet players — this fits bass clarinet only
- Anyone unwilling to buy a ligature and cap separately
- Players already settled on a custom-facing mouthpiece
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
B45 facing
Vandoren's most widely used facing. It's the common reference point when players compare bass mouthpieces.
Detail 03
Mouthpiece upgrade
Usually the single biggest tone and response change on a student horn — more than a new reed or ligature.
Detail 04
Hard rubber body
Standard material for clarinet mouthpieces. Stable and repairable, but it discolors if left in sunlight.
Final check
Know before you order
- 01Ligature and cap are usually sold separately — check what you already own
- 02Bass clarinet reeds are larger; your soprano reeds won't fit
- 03Give it a few weeks before judging — embouchure adapts to a new facing
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my bass clarinet?
Yes, it's a standard bass clarinet mouthpiece and fits standard bass clarinet necks.
02Does it come with a ligature and cap?
Ligature and cap are typically sold separately. Confirm before ordering if you don't already have a bass clarinet ligature.
03What reed strength should I use with it?
Most players start around 2.5 to 3 on bass clarinet and adjust from there based on air support and the sound they want.
04Is this worth it over the mouthpiece that came with my horn?
Stock mouthpieces on student bass clarinets are usually the weakest part of the instrument. A better mouthpiece typically improves response and low-register tone more than any other single change.
