Black Chrome special finish complete with presentation tin. A patented wrap-spring clutch mechanism – the original performance capo is suitable for all 6-string acoustic and electric guitars. The Performance Capos revolutionary new mechanism allows ultra-precise placement and clamping – without pulling the strings of your instrument out of tune. The capo is easily squeezed into place with one hand, and released using the lever on the back. When not in use, it stores neatly on the end of your instruments headstock.
