Detail 02
The beak is cut at a shallower angle than the traditional profile, so it feels slimmer against the top teeth.
Detail 03
Fits standard Bb soprano clarinets. Not interchangeable with bass, alto, or Eb clarinet mouthpieces.
Detail 04
Your existing barrel and ligature need to fit it. Reed strength may need rethinking too.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Only the beak angle. Profile 88 uses a shallower cut, giving a slimmer feel under the top teeth. The facing and tip opening are the same M30.
Most standard Bb clarinet ligatures fit, but ligatures are sized to mouthpiece body dimensions. Check yours seats and tightens evenly before relying on it.
Start near where you are now and adjust. A different tip opening changes the resistance, so you may end up a half step softer or harder.
Yes. Stock mouthpieces included with student clarinets use loose tolerances. A defined facing like the M30 gives more consistent response and intonation.
