Locking Machine Heads (6 Left, Machine Polised, Chrome)

Works like a traditional machine head, but the string needn't be "wound up" any more. Instead it is inserted into the cam hole with the clamp screw loosened, locked with the clamp screw and can then be tuned at once.

Makes changing your strings a lot faster and easier

Patented locking system based on the ball socket principle prevents reliably from string notching and breakage

Perfect for non-locking tremolo systems
