This reed is designed to produce a quality of extremely pure sound due to a very thin reed tip (the area of Reed with maximum vibration), being balanced by a solid vertebral column (more cane in the area which climbs gradually to the heel). These reeds are recognizable by a straight line to delineate the limit of the area of bark. The favorite reed of classic saxophonists worldwide since marcel Mule, it has always been (and is still) used with equal success by many players.
