True Lok

True Lok series tuning keys were designed to deliver impeccable tuning stability.  With options available for most vintage and modern guitars, every player can upgrade their instrument for Lok-solid performance!

Bulk Option

True Tune and True Lok tuning keys are now available in 10-set bulk packaging options, made to accommodate OEMs, small builders, and repair shops who see an ever-revolving door of tuner installations and replacements but don’t want the headache of dealing with unnecessary packaging.  Each box comes with 60 keys, enough to make 10 full 6-string sets, loaded into 2 foam inserts with a small cutout that secures the supporting hardware in place, ensuring nothing is scratched.  Allparts is proud to be serving the OEM and small builder community and to be the home of “premium tools for tone!”

Mid-Size 6-In-Line Locking

Designed for stability, accuracy and rigidity, our True Lok Mid-Sized 6-in-line locking tuning keys feature staggered posts that eliminate the need for a string guide, an 18:1 gear ratio for more accurate tuning, and an easy-to-use lock wheel on the back of the key that offer better tuning stability as well as making string changes quick and easy.  Designed to be more compact than full-sized keys for use in smaller 3x3 headstocks, these keys offer a sleek, modern look that would complement any guitar!
