The new M/O ligature 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.
• Inverted tightening with only 2 small contact points on the reed.
Thus, the M/O ligature allows an optimum vibration of the reed and a crisp articulation.
