Rotomatic® tuners that automatically lock the string as you tune. For 3-left/3-right pegheads.

Internal-cam locking string posts and 18:1 fine tuning are built into Rotomatic midsize cast housings to fit 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.
Also available for 6-in-line pegheads.

These midsize Rotomatic tuners feature compact metal knobs with adjustable tension, lifetime sealed lubrication, and 18:1 gear ratio for fine tuning. Sets of 6.

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

'62 Epi lockers

By Soreliprick from CA
(Customer's Reviews) Friday, April 04, 2014

Read the instructions! They work great but it wasn't enough to keep my Crestwood Custom in tune with my Washburn wonderbar trem unit. I got a locking nut from Kahler, cut tiny pieces of feeler gauges, .003, ..008, and .010 to compensate for string diameter with 2 to each Allen screw, glued them in place with superglue, and I can now dive 2 octaves on the fat E with no tuning necessary! I'll probably put them on my '72 D-18, which has the regular mini Grover's.

Direct drop in replacement tuners for prs se guitars. I might put these onto my prs baritone also once I confirm the max string size that these can take.

Awesome tuners for the Traveler Sportster guitar!

By George R from USA

I had recently purchased a Traveler Sportster guitar as a nice addition to my collection. As most owners may or may not know that even though this guitar is well-built,the Achilles Heel of this guitar is the tuners. The original tuners looked pretty good, but they slipped so much that I had to tune it constantly. I looked online to see what other Traveler owners did to remedy this & found that they suggested using Grover Mini Locking tuners. After I received them from Stew-Mac, I installed them onto the guitar. The whole operation took me 45 mins, as I was being very careful not to mess up. The tuners fit perfectly. I had to mount the tuners at a slight angle so the screw-eyes would have some room to screw into the wood. The tuning is now rock solid. Figuring out how to lock the strings is a breeze,thanks to the nice detailed instructions included. I highly suggest any owner of the awesome Traveler Guitar to ditch the stock tuners & get a set of these locking tuners. This is probably the best mod for these guitars.

Anyone buying their first guitar listen up!

Do not purchase an expensive guitar. Instead buy a medium priced guitar and put the money you saved in to a great set of tuners. Why? I put the Grover Mini Locking Rotomatics 3L/3R tuners on my ôbrand newö Breedlove acoustic guitar. A good guitar is important, but keeping a guitar in tune (professional and beginners alike) is MOST important. I remember when I began to learn to play, I spent more time trying to tune my guitar then I did practicing. For a beginner, how do they know if they are playing a chord wrong or if the guitar out of tune? I am a accomplished guitarist. I just purchased a Breedlove C250CM. This is an entry level guitar from a company who make only ôhigh endö guitars and one great affordable guitar, mine. I put the premium Grover Mini Locking Rotomatics 3L/3R tuners on mine. Now I have a ôhigh endö guitar. When you buy a guitar CHANGE the tuners! You will not regret it.

I purchased these to replace the Grover tuners on a Burns Brian May guitar. They work perfectly! They keep the guitar almost perfectly in tune and don't drift from day to day. I was surprised to find the guitar still in tune after sitting in it's case for a week. Buy with confidence. These work!

They look great and work flawlessly


By C. Bauman from Madras, O R

I installed these tuners on a Gibson 165 acoustic guitar. Installation required drilling new mounting holes because the bases on the locking tuners are larger than the standard models. They are smooth and attractive. Replacing strings is fast and easy. I am happy with the purchase.
