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
Fits Bb soprano clarinets. It will not seat correctly in an Eb, alto, bass or contrabass barrel.
Detail 02
The name identifies one specific facing and tip opening, so a replacement years later plays the same.
Detail 03
Your existing ligature and cap carry over if they fit a standard Bb clarinet mouthpiece body.
Detail 04
Component-level upgrade. Changes response and reed feel far more than a new case or swab would.
Detail 05
Same maker as the reeds most players already use, so reed strength charts line up with the mouthpiece.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Yes, it is cut for Bb soprano clarinet and seats on a standard Bb barrel. It will not work on Eb, alto, bass or contrabass clarinets.
No. This is the mouthpiece alone. Most standard Bb clarinet ligatures and caps will fit, but check yours before your next playing session.
Reed strength is personal and often shifts after a mouthpiece change. Start with what you play now, then try a half step up or down.
Yes. Stock mouthpieces included with student clarinets are the cheapest part of the instrument, and replacing one is the usual first upgrade.
