Because of the low angle of the string over the nut, string trees may be used to avoid the string coming out of the nut while playing. Fender usually uses non-angled, straight headstocks. This makes the neck and headstock easier to manufacture they can be constructed from a single piece of wood. Straight headstocks form a single plane with a flat surface of the neck (and fingerboard).The advantages and disadvantages of both trends are very debatable and subjective, so these two variants are used: There are two major trends in headstock construction, based on how the string will go after passing the nut. The headstock may be carved separately and glued to the neck using some sort of joint (such as a scarf joint).
Note the β angle between the surface of the neck and the headstock surface Schematic section shows both straight and angled headstocks.
