In the world of capos, the G7th Performance 3 ART capo stands out from the crowd. And now, with the Performance 3 Special-edition Celtic, you get a capo that celebrates the Emerald Isle and its rich musical history with a beautiful Celtic knot on the rear and top bar that was designed by renowned artist Patrick Gallagher. This innovative capo represents years of research and design strategy. With G7th's patented Adaptive Radius Technology, the Performance 3 ART capo actually adapts to the unique radius of your guitar, eliminating the two most common issues that arise with capos: fret buzz from not enough tension and strings that are bent sharp from too much tension. This stunning capo also features an easy squeeze-to-release mechanism that lets you slide it up and down the neck quickly.
