Designed specifically for classical guitars and other instruments with flat (non-radiused) fretboards, the NS Lite Classical Capo assures buzz-free, in-tune performance at any fret. A micrometer adjustment mechanism allows you 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. Molded ABS construction offers lightweight ease-of-use, and superior functionality at an affordable price.
