Detail 01
Locking posts
The string clamps in place instead of wrapping the post, so there are no coils to stretch and slip out of tune.

Independent shopping perspective
Locking tuning machines for Fender-style guitars. For players who break strings often, use a tremolo, or restring under time pressure.

Detail 02
Intended for Fender headstocks. Hole diameter and mounting still need to match your specific guitar.
Detail 03
Covers a full standard Fender headstock. Three-a-side headstocks need a different configuration.
Detail 04
Pull string through, clamp, tune. Cuts string changes to a fraction of the usual winding time.

Product questions
Straight answers to the questions shoppers most often ask about this product.
Not always. Import guitars often use different post hole diameters and screw placement. Measure your headstock holes before ordering.
They remove slippage at the post, which is one cause of drift. If your problem is a binding nut or old strings, they will not help.
Possibly. Post hole size and mounting screw locations vary. Some installs are drop-in, others need reaming or new screw holes.
Feed the string through the post, pull it taut, tighten the locking mechanism, then trim the excess and tune to pitch.
