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
An intermediate step between 3.5 and 4. More resistance, more control and projection, but it demands more air and a settled embouchure.
Detail 02
Sized and shaped for the Bb soprano clarinet only. It won't seat properly on bass, alto or Eb mouthpieces.
Detail 03
Cane varies piece to piece. A box of ten usually yields a few strong performers, several usable, and one or two duds.
Detail 04
A natural material that swells and dries. Reeds need break-in, rotation between several, and eventually wear out and need replacing.

Product questions
Straight answers to the questions shoppers most often ask about this product.
It's a half step between 3.5 and 4. Slightly more resistant than a 3.5 without the jump to a full 4.
No. These are cut for Bb soprano clarinet. Bass clarinet uses a larger reed and needs its own box.
Depends entirely on how much you play and how you rotate. Playing a different reed each day makes ten last far longer than favoring one.
Only if 3.5 feels loose, thin at the top, or hard to control at volume. If you're struggling for air already, stay where you are.
