The D’Addario Artist Capo utilizes a patented trigger geometry reducing the force required to open and close the capo while applying even tension regardless of neck profile. Combined with the micrometer tension adjustment and direct horizontal pressure, the Artist Capo virtually eliminates pulling the strings side to side and the need to retune during use. Additionally, the capo features our revolutionary FlexFit™ pad technology that applies individualized pressure to each string accounting for string gauge and fretboard radius, so you never have to worry about unwanted buzzing, muted strings, or intonation issues caused by varying capo pressure. With minimal overall pressure every string rings clear, clean, and in tune. The capo’s trigger design and lightweight aluminum construction adds no obstruction or noticeable weight to the neck of the instrument.
