New capo from Paige is on and off quickly, but with the same balanced tension their original capo offers. Push the center thumbscrew 'til it touches the neck, twist it a half turn or so and you're in business. To release, untwist a bit, then push the round button to completely release tension. SPECS: Width 2-1/16, Open Depth 1-1/8, Closed Depth 13/16. Fits to the 10th fret on a standard 1-11/16 neck. Can be used on wider profiles, but not as far up the neck.
