Designed to simulate DADGAD tuning on standard tuned guitars, the NS Artist DADGAD 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 NS Artist DADGAD Capo virtually eliminates pulling the strings side to side and the need to retune during use. Additionally, the trigger design and lightweight aluminum construction adds no obstruction or noticeable weight to the neck of the instrument. An NS Mini/Micro Tuner mounting bracket is included, allowing you to add tuning capabilities to the capo. Tuner sold separately.
