Guitar Locking Roto Chrome 3/Side GV-502C

The Chrome 3-per-side Grover Locking Rotomatic 502C tuners feature locking machine heads that utilize the famous 18:1 Rotomatic design with a “thumb screw” mechanism which locks the string into place. Insert the string through the post-hole, wrap around once, then lock by tightening with the thumb screw. This is the perfect replacement for the most standard machine heads and it includes all mounting hardware.
