Unique patented design where the bed of the reed curves down to allow the flat carbon-fiber tongue to vibrate. Avoids the problem of a settling reed tongue. The bed of the reed may be adusted by screws located on the underside of the reed. Replacing the traditional bridle is a metal tuning clip adjusted by a screw. Pitch is adjusted by a soft rubber tuning plug (unthreaded). Combines metal, carbon-fiber, rubber and plastic.
