Abstract
An adapter system for a stringed musical instrument having a tuning key and a string connected to the tuning key for adjusting the pitch of sound rendered by striking the string attached to said key. A limit stop is operatively mounted on the instrument along with a,rotational stop mounted on the key for interacting with the limit stop to confine the rotational movement of the tuning key to a certain predetermined arc. The limit stop can be adjusted to selectively change the angular arc. An internal adapter cylinder is operatively mounted on the shaft of the tuning key where the tuning key shaft is of a non-circular configuration. An upper cylinder and a lower cylinder are operatively mounted with respect to the internal adapter cylinder. The adapter cylinder is provided with a recess which accommodates a cylindrical insert used when the tuning key is not provided with a shoulder portion.
