Grover Roto-Grip Locking Rotomatics (505F Series) 6-In-Line Tuners

Drop-in replacement for your Strat!
Do you want the classic look and bulletproof performance of Grovers for your Strat? These high quality locking tuners drop-in with no modification! There's no need to drill or plug new holes and devalue your vintage guitar. In just minutes you'll stay in tune better than ever.

"Kluson-style" tuners on vintage and reissue Fender's look good, but get stiff and stop working over time. Finding a modern locking replacement without drilling new holes or reaming was difficult until now.

These tuning machines have a super-precise 18:1 gear ratio, and the rear thumbscrew locks the string to the post to stay in tune even during deep bends.

Grover Roto-Grip Locking Rotomatics 6-In-Line tuners feature:
• 18:1 gear ratio for precise tuning
• Locking string posts
• Cast gear housings with no-hassle lifetime sealed lubrication
• Traditional mini Rotomatic removable metal knobs
• Set of 6 includes mounting screws and round vintage-style press-fit peghead bushings

These directly replace any 6-in-line tuner with 4-11/16" (119.06mm) peghole spacing and 11/32" (8.73mm) diameter pegholes. These replace vintage-style Fender and Kluson tuners—always measure to make sure you'll have a perfect fit.

Installation Tips
Mounting screws: Pilot holes required. Installing delicate screws into hard wood requires great care and accuracy. We highly recommend the Depth-stop Drill Bit (5/64" bit) for the pilot hole before installing these screws. Lubricate the screw threads with cutting lubricant (also wax or a bar of soap) to reduce friction and help them thread properly.
