Internal-cam locking string posts and 18:1 fine tuning are built into familiar Rotomatic™ full-size cast housings for 3-left/3-right pegheads. As you tune, the post automatically locks the string. You'll need fewer string wraps, change strings faster, and your tremolo will have more accurate return-to-pitch.

These full-size Rotomatic tuners feature large removable metal knobs with adjustable tension, cast gear housings with lifetime sealed lubrication, and 18:1 gear ratio for fine tuning. Sets of 6, for 3-left/3-right pegheads.

Mounting screws and threaded hex peghead bushings with washers are included.
10mm (13/32") diameter pegholes required.

For 6-in-line pegheads, see Grover Mini Locking Rotomatics.

To be sure these tuners fit your instrument, compare your existing machines and peghole dimensions to our listed specs to help determine the best replacement.

Gold Grover

I got these to replace a set of non genuine tuners and they were super easy to install and screws lined up perfect, very happy! Just check the height they are a little bit taller than the others!

Great quality tuners

Theses tuners are absolutely top quality. The automatic locking of the string works really great. The ratio of the tuners makes it possible the fine tune to the perfect tone. My headstock is thin so the tuner shafts stick up a bit more than a normal tuner so if you have a guitar with a headstock that needs the string to be attached to the tuner near the face of the headstock these tuners could give you problem.

I Like these tuners a little better than the older thumbwheel lockers. They put less stress on the edge of the string, producing less chance of breakage.

Item # 0877 - Grover Locking Tuners Chroime 3L/3R

These are a brilliant locking tuner, nice and solid. Excellent high polish solid chrome plating. They are heavy by feel, so you have confidence in no movement when string is loaded, easy string insert and lock as you wind design. No slip and excellent geared motion. I recommend these to anyone

Locking Tuners for Resonator Guitars

I love to use the locking tuners on my Resonator Guitars. It's like having a third hand when you are trying to keep the strings in place as you tension. The quality is a given and my customers love them. Mike Franks Guitars

Great Grovers

The Orig. Grovers on my 335 were shot and leaking and I actually no longer trusted Grovers, but since they retrofit perfectly, I decided to try the locking tuners, assuming they'd be of higher quality. I've had them on for 2 years and am ordering a set for my other 335 even though the tuners are in fine condition. These lockers string so easy and stay in tune so well that it's well worth the swap.

Great buy

On my 2009 Gibson Les Paul Studio, there were no peghole modifications needed. it fits into the existing holes perfectly. All I needed to do was to drill new holes for the grub screws. They look great, feel great and more importantly, work great.

Grover Machine Heads

The machine heads are fantastic and great quality. Had to drill new holes for the grub screws. had them mounted in less than an hour. The posts are longer than standard posts, but the locking mechanism works well.

Epiphone Sheraton II - tuners

I just finished replacing the tuners on my Sheraton II with these locking tuners. I have them on my Epiphone Les Paul Tribute as standard feature. Easy change - less than 1 hour. You will need a 10 mm deep socket & small Phillips screw driver. The new screws provide with tuners were thinner than the Grovers that came with the guitar. I reused the original screws. I also reused the same strings. Now gig ready!
