<p>A fretboard adapted to be fitted to the neck of a stringed instrument is described. The fretboard comprises a unitary, elongate body having first and second longitudinally spaced ends to be arranged adjacent the body and head ends, respectively, of a stringed instrument, and a plurality of integrally formed frets in the normal fret positions. The frets comprise transversely extending crests of a plurality of triangular shaped ridges arranged in succession along a surface of the body from the first end to the second end. Each ridge comprises a relatively short side steeply inclined to the longitudinal axis of the body and a relatively long, substantially planar side sloping from the top of the short side to the base of the short side of the next following ridge in the direction of second end. The top of each short side, where it meets its associated relatively long side, is rounded with a centre of curvature located on an imaginary line extending substantially at right angles to the longitudinal axis of the body and passing through the crest of the associated ridge. The crest of each ridge has a hard, wear resistant surface.</p> |
