Clarinet Bb RC have a classic, French style filing. These reeds are made on a segment of 3.2 mm, rectified to 2.8 mm.

This leaves the scraping in the most vibrant area of the reed and produces a very brilliant sound. 

The material is stored to age for at least 3 years before its manufacture.

Its shallow shoulders have a closed half-moon shape.

This helps to maintain the tuning despite being an extremely flexible and spontaneous cane.
