Disclosed therein is a guitar string regulator. The guitar string regulator includes: a regulating lever (12) having a worm gear part (11) disposed at one side thereof; a casing (14) having a joining tube (14b), which has a male screw portion (14a) penetrating through the head (5), and a bearing portion (14c) formed on a lower portion thereof for receiving the worm gear part (11) and supporting rotation, of the worm gear part (11); a rotational rod (15) penetrating through the casing (14) and having a winding portion (15a), which is concavely formed at one side thereof for winding a string, a guide hole (15b), which is formed in the winding portion (15) and penetrates through the joining tube (14b) for inserting the string (W) thereinto, and a spur gear (15c), which is disposed at a lower portion thereof for rotating the rotational rod (15) in engagement with the worm gear part (11); and a nut (16) joined to the male screw portion (14a) of the casing (14) for fixing the casing (14) from the head (5), wherein the rotational rod (15) has a through hole (15d) formed at the center of the rotational rod (15) for inserting the remainder of the string (W) wound on the winding portion (15a) thereinto, The guitar string regulator can prevent interference by the cut end of the string, prevent the player from getting scratched or pricked by the cut end of the string, and can always make the head part of the guitar clean because the cut end of the string of the guitar is guided into the through hole formed in the rotational rod as soon as the string is cut close below the case after the remainder of the string penetrates through the through hole of the rotational rod.
