Detail 01

Sized for the bass clarinet neck only. It won't seat on a soprano clarinet, and bass reeds are required.

What matters in use
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 01

Detail 02
Vandoren's model code covers the facing length and tip opening as a matched pair. Two B44s play the same as each other.
Detail 03
The mouthpiece is one part of the setup. Reed strength and ligature choice will change the response as much as the piece does.
Detail 04
Standard for clarinet mouthpieces. More stable in pitch and warmer in tone than the plastic pieces bundled with student horns.

Product questions
Straight answers to the questions shoppers most often ask about this product.
Most players land between 2.5 and 3.5 on standard bass clarinet reeds. Start at 3 and adjust — softer if it feels stuffy, harder if the tone thins out.
No. This is the mouthpiece alone. You'll need a bass clarinet ligature and cap, which are sized differently from soprano clarinet ones.
It fits standard bass clarinet necks. If your cork is old or compressed the piece may sit loose; a re-cork at a repair shop fixes it.
Yes. Hard rubber mouthpieces are more consistent than the molded plastic pieces packed with beginner instruments, and the tone centers more easily.
