Designed for 6-string acoustic and electric guitars, The JOYO JCP-03 Light Capo is tough and sturdy enough to hold up to the countless hours of practicing and jamming. The silicone pad will also protect your fretboard from damage as well as prevent fret buzz as you play. The JOYO JCP-03 also has a great feature for acoustic players. This capo also has a bridge pin puller built in. Certainly a great addition for anyone changing their own acoustic guitar strings.
