"Awarded gold medals for most innovative new product and best overall capo in the 2008 Players Choice Awards, the G7th Performance Capo is a revolutionary new mechanism that allows ultra-precise placement and clamping without pulling the strings of your instrument out of tune. It's 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 instrument's headstock. This version is designed for 6-string guitars (both acoustic and electric). The G7th Performance for six-string guitars. The G7th Performance capo's patented clutch mechanism consists of just three elements: a fixed hub, a moving hub, and a spring whose inside diameter is just slightly smaller than the outside diameter of the two hubs. When the spring is forced over the two hubs, attempting to rotate in the direction which opens the capo wraps it down tightly on the hubs, positively engaging them. Rotation in the other direction, to tighten the capo onto the strings, is not restricted. To release the capo, the control tang is moved in the direction to unwind the spring, thus releasing the clutch.
