Abstract

A C-clamp capo comprises a string press for clamping down on the strings of a string-instrument against a front side of a fretboard. An extension arm curves behind and has an idler clamp with a first pivot attachment. Such enables a clamping action against a backside of the fretboard. A continuous insert having a positioning bumper that ensures consistent positioning against the fretboard is disposed all along an inside surface of the string press from a distal end across the first pivot attachment bridging over to an inside surface of the idler clamp and out to its distal end. A locking lever has a second pivot attachment to the extension arm behind the first pivot attachment, and provides a locking action against a backside of the idler clamp. A setscrew disposed in the locking lever provides an adjustable locking action between the idler clamp and the locking lever, e.g., for a range of thicknesses of the fretboard to be accommodated. A plastic, pointed tip on a distal end of the setscrew helps for a smooth engagement along a backside of the idler clamp. A grooved slot in the backside of the idler clamp provides a track in which the plastic, pointed tip of the setscrew is smoothly guided into a locking position. A depression located at a locking end of the grooved slot provides for a detent in the locking position.
