When they made the Dunlop Trigger Flat 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.
