Abstract
A stringed instrument system comprising a body having a headward edge, a tailward edge, a upper edge, a lower edge, a front and a back. A first fingerboard extends beyond the headward edge of the body and a second fingerboard is located entirely on the body. The first fingerboard includes a fretted surface. A track runs beneath each fingerboard edge. The capo has an axis of rotation eccentrically located within the capo. A slider attached to the capo reacts against the track surface and pulls the capo hard against the fretted surface when the capo has been cammed against the fingerboard. The fingerboards may be removably secured to the body so that they are interchangeable.
