for fifty years I use capos. This model is the first one I describe as almost perfect. It is narrow and therefore does not interfere with the hand. It is due to the adjustable wheel at the right tightening. The small wheel that the manufacturer has recently added allows to quickly remove the device and without difficulty. The new curvature of the lower arm is clever because it facilitates the release. If you choose the model nylon string guitar you will have no trouble to serve you with any electric guitar or another even twelve strings.
