When they made the Dunlop Trigger Curved Guitar Capo they knew your sound shouldn t change when you put on a capo and it shouldn t be a 12-step process either. With the Trigger capo you ll come through loud clear in tune and in less time. The Dunlop capo is made of aircraft-quality aluminum with a strong padded spring-action grip that can be changed quickly with just a squeeze. Works for both 6- and 12-string guitars. The Trigger Curved Capo features a unique pressure pad that conforms to fingerboard and frets for buzz-free fretting.
