A relatively new development, locking tuners are intended to complement vibrato systems. However, they can also have a benefit for instruments without vibrato systems: faster restringing.

You can view the installation of a set of locking tuners on a Fender Stratocaster in our series on setting up the Strat trem – Join us in Part 1
