The NS Capo Lite is made from high-strength molded ABS thermoplastic for use on acoustic and electric 6 string guitars. A patented micrometer adjustment mechanism allows the player to dial in the exact tension needed for your guitar, strings and playing position. This greatly reduces the need to retune your guitar during and after capo use. The capos molded ABS design offers light weight, ease-of-use and superior functionality at an affordable price. Enjoy buzz-free in-tune performance at any fret without breaking the bank! Also available in the NS Pro model featuring aircraft grade aluminum construction. The NS Series capos are the result of an ongoing collaboration between famed product designer Ned Steinberger, Jim D'Addario and the D'Addario Accessories team.
