Product questions
Straight answers to the questions shoppers most often ask about this product.
No. It's cut for A clarinet bore and tenon dimensions. Buffet makes a separate Moennig barrel for Bb.
It's cut to Buffet specifications. Other brands often have different tenon diameters — a repair tech can fit the cork, but check bore compatibility first.
Going from a 66 to a 65 raises pitch by roughly a few cents. Enough to stop constant pushing in, not enough to fix a major intonation problem.
Not required, but many players match tapers so response and resistance feel consistent when switching horns mid-concert.
