Designed specifically for classical guitars and instruments with flat (non-radiused) fretboards, the Artist Classical 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 Classical Capo virtually eliminates pulling the strings side to side and the need to retune during use. Additionally, the trigger design and lightweight aluminum construction add no obstruction or noticeable weight to the neck of the instrument. The Artist Classical Capo includes a micrometer tuner mounting bracket, allowing you to add tuning capabilities to the capo. Tuner sold separately.
