The D'Addario NS Capo is the product of an ongoing collaboration between famed product designer Ned Steinberger and J. D’Addario & Company. It employs a sleek ultra-light design for fast and accurate one hand positioning on the guitar’s neck. Just turn the smooth tactile dial to eliminate the string buzzing and enjoy perfect in-tune performance. Lightweight aluminum adds virtually no weight to the guitar’s neck when in use.
