Patented, unique Tension Control system - the simple intuitive squeeze-on, squeeze-off action means you can easily and quickly move the capo from fret to fret, or from guitar to guitar without any adjustment needed: just squeeze for optimum tension. Almost as fast to position as a simple spring capo ? but faster, because you don?t need to retune. Wrap around silicone rubber protects your neck from metal to wood contact. Safeguards your tone thanks to firm string pad material that reduces vibration damping. With Patented Adaptive Radius Technology (ART) Featuring ground-breaking Adaptive Radius Technology, coupled with the Unique Tension Control system found on all Performance series capos, the Performance 3 is our flagship capo. New active string pad infinitely adapts to match any guitar perfectly. The ART mechanism delivers unrivalled tuning stability by applying even pressure across the strings.
