Abstract

A stringed musical instrument comprises a neck and a cavity formed in the neck. The cavity includes a curved bottom surface and a chamfer in a sidewall of the cavity. An island is formed in the cavity. A fretboard is formed comprising a veneer and adapted to fit the cavity. The fretboard includes an opening adapted to encompass the island in the cavity. The cavity or fretboard is formed using a computer-controlled or numerically-controlled milling machine, router, water jet, or laser. The fretboard is mounted within the cavity, and the island in the cavity is disposed within the opening in the fretboard. Mounting the fretboard within the cavity includes flexing a sidewall of the cavity. An edge of the fretboard contacts a sidewall of the cavity without a visible gap.
