This UK patent describes an improved guitar headstock tuning system where each machine-head has a rotatable winding peg and an adjusting handle whose axis of rotation is inclined rearwardly relative to the plane of the fingerboard and is non-parallel to the winding peg axis. The invention also incorporates the handle axis being inclined at an acute angle relative to a perpendicular to the longitudinal axis of the instrument, generally toward the sound box. This design improves ergonomics by allowing the tuning handles to fall naturally to the player's hand without requiring uncomfortable wrist flexion.
