The C3 is specifically designed to suit 12-string guitars, or any steel string guitar with a wide fretboard.
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 it doesn't pull the string off center. As a result, no re-tuning is necessary!
Width: 2-1/4"; Curved for a radiused fretboard; Nickel finish
