True Lok

Explore True Lok Mid-Size 3x3 locking guitar tuners at Palm Harbor Music. This tuning-machine set uses a three-per-side headstock arrangement, an 18:1 gear ratio, and locking wheels that secure the strings in the posts.

The listing describes die-cast zinc housings, steel worm gears, brass gears, and 6mm string posts. Included mounting hardware consists of six screw-in bushings, six dress washers, and six screws. Compare the mid-size housing dimensions and mounting requirements with your existing tuning machines when planning a replacement or guitar build.

Before purchasing, confirm headstock layout, mounting-hole diameter, bushing dimensions, post length, headstock thickness, and screw positions. The stated string-post diameter does not establish the required headstock-hole size. Review the product listing for specifications and installation details rather than assuming a universal or modification-free fit.
