The Shubb Original C-Series 12-String Capo is 2-1/4" and slightly curved to better fit any steel string guitar with a wide fretboard. Choose either nickel-plated or plain brass finish. The Original C-Series capo features a patented locking action that provides an unrivalled combination of power, speed, accuracy and ease of use. One smooth flip of the lever locks the capo securely in placeand removes it just as quickly. And the Shubb 12-string capo doesn"t create tuning problems. Its soft, resilient rubber is specially designed to work just like a fingertip, so it doesn"t bend the strings over the frets. Its closing action is just like your hand, so the Shubb Original C-Series 12-String Guitar Capo doesn"t pull your stringa off center. As a result, no re-tuning is necessary.
