The latest from Vandoren for clarinetists, I was looking for an opening and a perfectly cut chamber to solicit more effects ... and here I admit for the moment to be skeptical because it seems necessary to considerably lower the strength of the reeds. Apart from this question which remains unanswered for the moment, after a few minutes searching for a suitable reed and a different position in the mouthpiece grip, this mouthpiece is a jewel of power, in my opinion mainly suitable for playing contemporary (amplified) music and in section. For street performance musicians, it seems that Vandoren has released the product you need.
