The headstock, located at the farthest end from the guitar body, holds machine heads that adjust string tension affecting pitch. Traditional layouts feature 3+3 tuners, while others have six-in-line or 4+2. Some guitars lack headstocks, relocating tuning machines to the body or bridge. The nut, a strip of bone or plastic, guides strings onto the fretboard and is crucial for accurate string placement and tuning. To reduce friction, some guitarists use roller nuts. The neck comprises the frets, fretboard, tuners, headstock, and truss rod. The wood used differs for the fretboard. Neck resistance to bending is vital for maintaining pitch. Neck shape varies from C to V curve, with different profiles available. Neck width, scale length, neck wood, construction type, and neck profile are aspects to consider in a guitar neck. Materials like graphite, aluminum, or carbon fiber are used in some necks. Double-neck guitars allow quick switching between sounds. The neck joint or heel connects the neck to the body, with common types being mortise and tenon, dovetail, and Spanish heel joints. Bolt-on necks offer flexibility and easy maintenance. Neck-through-body construction provides better sustain. Instruments may have a neck and sides built as one piece or a body built around the central neck piece. The fingerboard, made of wood, metal frets, or composite materials, is flat on classical guitars and slightly curved on acoustic and electric ones. Fretboard curvature is measured by radius, with smaller radii creating more noticeable curves. Pinching a string against a fret on the fretboard shortens its vibrating length, producing higher pitches.
