Rotomatic® tuners that automatically lock the string as you tune. For 6-in-line pegheads.

Internal-cam locking string posts and 18:1 fine tuning are built into Rotomatic midsize cast housings to fit 6-in-line 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 3-left/3-right 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.

Schaller Killers

By Bill Palmer from Australia
(Customer's Reviews) Thursday, October 03, 2013

I much prefer these over the Schaller type with the locking screw. These "just work" and the feel is excellent. Money well spent

I like the locking mechanism. You need to read the directions, and understand how they work. They seem lighter and smaller than the locking tuners with the knob on the bottom. You do not notice that these are locking tuners. I would buy them again.

Have always been a fan of Grover (at least 4 of my guitars have them). This is the first time I have used the mini locking tuners. Perfect fit on my "Beijing Tele" even the wood screws aligned perfectly. Easy to restring with these, like having an extra hand.

60 years guitar playing and they re- invent the wheel. Grover Locking Rotomatics fit right onto my Vietnam Tele, same screw holes and they work with one minute string change and stay entune. I put new period piece Grovers on my 52 SJ and my 56 J 50 but I wish they were lockers too. Thanks Stew Mac. You make me sound good.

They work great

I recently bought an SX Furrian Tele style guitar as a project to mod into the Telecaster that Fender never made for me. The very first thing I bought was this set of locking tuners. They are a drop in replacement for the so so ones that come installed on the guitar. I've watched videos online of people trying to play a whole song without having to re-tune and not being able to do it. I just sprung for the tuners up front and at the same time that I ordered the guitar. They got here a day before the guitar did. It took me less than half an hour to install them and restring the guitar. It stays in perfect tune. Since I didn't like the chrome that the cheap hardware on this guitar comes with, I decided to powder coat all the chrome with translucent gold and rainbow hued sparkle including the new tuning pegs and washers and nuts. Now, replacing the plastic nut is next.....

Very nice

These are very good tuners. The lock mechanism is simple and robust, and they are silky smooth.

I bought these tuners several years back they are great! I have them on a Strat I built several years ago. I can dive bomb on the wammy bar all night and rarely have to tune up. Great product!

cool how the strings lock in makes for a quick change-out,and 18:1 ratio keeps in tune real well
