Charles Bay ligature for bass clarinet, made by an American manufacturer. Rhodium-plated, single-screw design. Made of very thin metal, it responds well, allows for easy breath control, and allows the reed to vibrate naturally. The appeal is that the ligature's influence is minimal, in a good way. The rhodium plating and single-screw mechanism contribute to a more unified sound. There is some discoloration of the plating, so it is listed as having dirt and scratches, but there are no scratches or distortions that would interfere with use. Thank you!
