ABSTRACT:
A capo composed of a semi-circular yoke, a bar pivotally connected at a first end to a first fork of the yoke and releasably interlocked at the second end to a second fork of the yoke via intermeshing of opposing slots oriented at ninety degrees to each other, a clasp mechanism located on the second fork for releasably locking onto the second end of the bar, a screw operated foot connected with the yoke, and dual guide bars connected at either side of the foot which movably engage slots located in the yoke. The capo provides for a simultaneous compressive force being applied to each of the strings of the instrument fretboard because the bar is connected with respect to the yoke and the foot at an angle so that it will engage the strings uniformly and simultaneously as the screw is tightened.
