G7th Performance Capo
The G7th capo is a completely new approach to capo design. It has none of the disadvantages of conventional capos, but instead offers enhanced performance and is simple to use.
The G7th capo has a unique one-way cam that lets you adjust tension in tiny increments with a squeeze. Unlike every other capo out there, it can apply enough tension to cleanly fret the string without bending it sharp. Works on acoustic and electric guitars equally well.
