The innovative pressure ribs minimize reed/ligature contact, enhancing tone, dynamic range and carrying power. Muncy Winds offers these ligatures in Standard (screws on the reed side), Inverted (screws on top of mouthpiece) or Inverted Cut Away (center is cut out)and in 3 different finishes, Nickel, or Silver plated. The Inverted Cut Away allows the reed to vibrate even more freely as it only contacts the reed from 4 smaller pressure points not the entire rib. The Silver Plating helps to prevent the ligature from slipping upwards off the mouthpiece.
See Detailed Images Below and the link to purchase the Bonade mouthpiece cap. (Standard caps do not fit the inverted Bonade ligatures.)
