Banjo/Mandolin accessory. Made by Kyser. Kyser's Quick-Change Capo is made of strong, light-weight aluminum. The spring-tensioned Quick-Change clamps firmly to hold intonation, but is quickly and easily released and repositioned without disturbing the tuning. You can operate your Quick-Change comfortably with one hand. You'll find that it doesn't interfere with fingering and the pads won't mar or react with guitar finishes.
