The Chadash clarinet barrel is produced and distributed by the Buffet Crampon company. The unique, two-stage reaming process of the Chadash barrel features a poly-cylindrical bore that improves focus and eliminates sharpness in the throat tones. The barrel, made from hand-selected unstained Dalbergia wood, is of the highest quality that Buffet has in their stocks in Paris.

The Chadash barrel is a reverse tapered cone bore similar to the "Moennig" barrel, but with a very slow progression of the taper. The boring process for each barrel is done with a single-edged French-style reamer that involves two different passes with the borer followed by the polishing of the bore.
