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
Thicker blank and longer heel than the traditional cut. Darker sound, more resistance at the same numbered strength.
Detail 02
A half-step between 3.5 and 4. Meant for players who outgrew 3.5 but stall out on 4.
Detail 03
Ten reeds per box. Typical for cane, only some of a box plays well, so buy in tens rather than singles.
Detail 04
Cut for Bb soprano clarinet. Will not fit bass, alto, or Eb clarinet mouthpieces.
Detail 05
Natural material. Responds to humidity and needs breaking in; strength varies slightly reed to reed.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
It is a half-step between 3.5 and 4. Vandoren adds these intermediate strengths so players who find one number too soft and the next too hard have somewhere to land.
V12 uses a thicker blank cut from the same cane, with more material at the tip and a longer heel. The result is a darker tone and more resistance at the same number.
No. These are cut for Bb soprano clarinet. Bass clarinet takes a larger reed.
Wet the reed before playing, and start new reeds with short sessions rather than a full rehearsal. Cane needs to stabilize before it settles into a consistent response.
