The new ligature M/O combines the lightweight construction of the legendary Masters ligature with the highly efficient tightening of the OPTIMUM ligature.

• Lightweight 
• Easy to set up 
• Quick and symmetrical tightening with a unique double-track screw mechanism 
• Two small contact points only on the reed with an inverted tightening 
  
  Thus, the ligature allows an optimum vibration of the reed and a crisp articulation.
