The Quik Change II is a screwed to the guitar top and retains the strings at the bridge end. Ball end strings can be quickly fed into the tailpiece and once attached to the tuning machine are held securely by the ball. The height of the mounting posts is adjustable. The Quik Change II relies on a separate bridge which allows the string height and intonation to be adjusted. It is often used in conjunction with a Gibraltar II Tune-O-Matic style bridge. The Quik Change III replaced the Quik Change II in the early 2000s.
