The ART system within the top bar of the Performance 3 capos mechanically adapts to the true curvature over your strings and fretboard, exerting completely even pressure across all the strings - setting a new standard of in-tune, buzz-free use. It gives you maximum tuning stability with the minimum possible tension in EVERY position, on ANY guitar neck. By simply squeezing to attach and squeezing to release, the Performance 3 capo gives you complete and intuitive control over the pressure you place on your strings. Whether it's an acoustic or an electric, you can have confidence that you are in control and will keep your guitar in tune. With non-reactive, protective silicone pads at every touchpoint, you can be sure that the finish on your instrument is safe when using a Performance 3 capo. Between songs, you can easily park a Performance 3 capo on the headstock or just behind the nut for quick and convenient access. With a little practice, a Performance 3 can be moved with one hand between frets nearly as quickly as a spring capo, but without the need for frequent retuning.
