Shubb C3 Standard 12 String Capo
 
The C3 is not only for 12 string guitars but for any guitar with a wide fretboard.  The C3 is 2.25" wide and curved.
 
When the Shubb capo was first introduced about 40 years ago, guitarists throughout the world fell in love with it. They’re still in love with it today. We’ve given it a few tweaks through the years, but its basic mechanical principle remains the same: a unique over-center locking mechanism that provides an unrivaled combination of power, speed, accuracy and ease of use. One smooth flip of the lever locks it securely in place, and removes it just as quickly.
