Tuners - Grover, Vintage, for Fender, Roto-Grip

The 505FV series design allows you to upgrade your vintage Fender® tuners to a more modern style locking tuner without making ANY modifications to your guitar. The overlapping ear design allows you to utilize the existing screw holes and the use of push in bushings, rather than screw in, means no modifications have to be made to the post holes. These inline tuners feature the famous 18:1 ratio and thumb screw locking mechanism.

Note: If building a new guitar or retrofitting a guitar for vintage style tuners, a 21/64” drill bit is suggested by Grover if the holes need to be drilled or re-drilled for the required .328” hole.
