Designed for use on 6-string electric and acoustic guitars, the black NS Tri-Action Capo assures buzz-free, in-tune performance at any fret. The patent-pending Tri-Action Geometry reduces the force required to open and close the capo and applies even tension regardless of neck profile. Combined with the micrometer tension adjustment that ensures the proper force is being applied to the neck of the guitar and direct horizontal pressure, the Tri-Action Capo virtually eliminates pulling the strings side to side and the need to retune during use.The single hand, easy to operate Tri-Action Capo clamps to the headstock when not in use. An integrated pick holder stores your pick in a convenient location when playing fingerstyle. It is constructed from aircraft grade aluminum making it rugged enough to take a beating, but very lightweight on the fretboard. It adds negligible weight to the neck of the instrument and will not damage the finish.For over 20 years, D?Addario has been leading the industry in innovative and problem-solving products that serve musicians worldwide.
