Detail 02
The reverse-taper bore is the point. It tightens response across registers and evens out throat tones.

Product questions
Straight answers to the questions shoppers most often ask about this product.
It's cut to Buffet Bb specifications, so yes on Buffet Bb clarinets. On other brands the tenon diameter may differ enough to need a repair tech to fit.
Depends on where you sit at pitch. If you're consistently sharp and pulling out at the barrel, go 67. If you're at pitch or flat, stay at 66 or shorter.
Yes. Barrel bore shape and length affect resistance, response, and intonation across registers — most noticeably in the throat tones.
No. This is the Bb version. Buffet makes a separate Moennig barrel cut for A clarinet.
