The Shubb C5 is a nickel-plated banjo capo. Designed for instruments with flat fretboards, it will also fit most mandolins. The Patented locking action provides an unrivalled 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. 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 it doesn't pull the string off center. As a result, no re-tuning is necessary! For banjos and most mandolins. Nickel-plated.
