Made of durable black anodized aluminum, the Reed Machine is accurate to +/- .001" and is guaranteed to copy any reed - commercial or handmade. Once a guide reed is accurately placed on the left side of the table and a blank is properly placed on the right, the copying can begin of any E-flat clarinet, B-flat clarinet, Soprano saxophone or Alto saxophone reed (attachment sold separately). With a mere movement from left to right, fine strips of cane are removed from the blank until a new reed is formed. After clipping, the reed is ready to play! For full instructions on the Reed Machine please click link. Three styles of precision Teflon guide reeds are also available. The Reed Machine table has a removable insert that can be replaced with any of these guide reeds.
