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
Firm and resistant. Needs a developed embouchure and air support; it will feel stuffy if you are not there yet.
Detail 02
Vandoren's original profile with a thin tip and thicker heart, aimed at a focused, centered classical tone.
Detail 03
Sized and profiled for a bass clarinet mouthpiece. It will not seat correctly on a soprano clarinet.
Detail 04
Enough to build a rotation, which extends reed life compared with playing one until it dies.
Detail 05
Natural material, so strength varies slightly reed to reed within the box.

Product questions
Straight answers to the questions shoppers most often ask about this product.
If you are not already comfortable on 3.5, yes. Strength 4 demands developed air support and embouchure to speak freely.
No. These are cut for bass clarinet mouthpieces and are larger than soprano Bb clarinet reeds.
Five.
Traditional is the original profile — thin tip, thicker heart — for a focused, centered tone rather than a brighter, more flexible response.
