The Shubb Original C-Series Nylon-String Capo is 2-1/4" wide and perfectly flat. This is an ideal capo for classical guitars or any with a flat fretboard. The Original C-Series Capo features a patented locking action that provides an unrivaled combination of power, speed, accuracy and ease of use. One smooth flip of the lever locks it securely in placeand removes it just as quickly. And the Shubb C-Series capo doesn"t create tuning problems. Its soft, resilient rubber is specially designed to work just like a fingertip, so the capo doesn"t bend the strings over the frets. Its closing action is just like your hand"s, so the Shubb Original C-Series Nylon-String Guitar Capo doesn"t pull strings off center. As a result, no re-tuning is necessary.
