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
Warmer and less brittle than plastic, and stable in pitch once warmed up. Reacts to heat, so avoid leaving it in a hot car.
Detail 02
The beak angle is 88 degrees rather than the older 84. Less lower-lip pressure and a more upright horn angle for many players.
Detail 03
Wider than most student mouthpieces. Gives more volume and flexibility but needs steadier air to keep the tone centered.
Detail 04
Sized for a standard Bb soprano clarinet. It will not fit bass, alto, or Eb clarinets.
Detail 05
Facing and chamber are consistent unit to unit, so a replacement years later plays close to the one you have now.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Most standard Bb clarinet ligatures fit. Ebonite mouthpieces are a common size, though tight metal ligatures cut for a specific brand can sit slightly high or low.
Players often drop about half a strength from what they use on a student mouthpiece, because of the wider tip opening. Try a couple of strengths and pick what speaks cleanly.
Profile 88 has an 88-degree beak instead of 84. The clarinet sits at a slightly different angle and many players find less lower-lip pressure is needed.
Swab it after every session and rinse occasionally in lukewarm water with mild soap. Hot water and alcohol dull the finish and can warp the facing.
