Paige Clik PC-6-W-ETI 6-string Wide Guitar Capo Paige’s Clik ETI (Enhanced Tone Innovation) capos are specially designed to require minimal pressure across the strings by utilizing a slotted tension bar that’s similar to a guitar’s nut. A fine-tuned tension wheel and a quick-release button make the Clik ETI great for players who move their capos around often during a set. Guitar Capo Features: Unique patented design Controllable tension No string buzz or muting Moves quickly and easily Conveniently stores behind the nut ETI bar Size: Width: 2 1/4” (2.250) Open Depth: 1 1/8” (1.125) Closed Depth: 11/16”. For wider profile necks, works well on 1 3/4, 1 13/16, & 1 7/8 necks Radius: Radius of bar 16” Traditional capos can have a tendency to throw your guitar’s tuning out of whack; designs that utilize a solid tension bar apply even pressure across all the strings, and this can be an issue as significantly less pressure is required to depress lower gauge strings than higher gauge strings. Paige’s ETI solves this issue by replacing the classic bar design with a system that looks just like a guitar’s nut ? only flipped upside down. Each slot is individually molded for each string: this, combined with the tone bar’s radius, allows the Clik ETI to apply only the absolute minimum amount of string pressure required to produce a clean note. The result? Youre always in tune!
