## Description

Grover Rotomatic 406C locking guitar tuning machine heads give you easy tuning and positive string locking. With a gear ratio of 18:1, these locking tuners serve up all the goodness of standard Rotomatics - plus Grover's internal cam post. Stick the string through the string hole, hand pull to tension, and begin tuning. As you start to tune, only the locking cam inside the string post turns. The string post itself starts turning once the string is locked. In under one revolution of the string post, you'll be in tune - and you'll stay that way! Upgrade your axe with Grover's Rotomatic 406C locking guitar tuning machines.

Review: Great locking tuners. - Love these Grover Rotomatics. Fit my PRS SE Custom 24 perfectly. Easiest locking tuners to make string changes once you know the secret of how to align the internal cam holes......turn the post till you feel the click.
Review: Great Replacement Gretsch Electromatic - Great product. Wasn't quite sure how it worked. Watched a quick video on it. About as easy as it gets. Installed them on a Gretsch Electromatic without any modification needed.

## Questions & Answers

**Q: Will these fit a Taylor 210ce?**
A: They will fit fine, and if you want to maintain the stock appearance of the Taylor 210ce, save the knobs and screws so you can put them on the new Rotomatics. I did that with a PRS SE Custom 24 and a Michael Kelly, Les Paul style guitar that I upgraded.

**Q: Fit a Gretsch g5222 ?**
A: Yes!

**Q: Can you purchase larger tuning keys for the tuner?**
A: Yes type in the search for “Grover tuner buttons”
The regular rotomatic buttons are larger and the hipshot buttons should fit as well

**Q: will these tuners fit a 1981 les paul fire brand guitar ?**
A: They would work, but Les Paul guitars use Kluson tuners so the mounting holes on the Grovers will not match the original holes, and probably won't completely cover the existing holes. Also the holes in the head-stock may be a different diameter. You would be better off replacing the original tuners with these: Kluson Revolution 3X3 Locking Tuners, Keystone Buttons - NICKEL, for sale on Amazon for $88.79 with Perloid buttons which are probably like the originals, and will install without modifications. I used The Kluson locking tuners on an Oscar Schmidt OE35 which is a Gibson ES 335 clone and they work perfectly.

### ⭐⭐⭐⭐⭐ Great Replacement Gretsch Electromatic
*by P***E on July 10, 2025*

### ⭐⭐⭐⭐⭐ Best Case Scenario
*by A***R on December 28, 2023*

Perfect replacements for my Orangewood "Oliver" OM size acoustic. Instalation was a breeze... they were a perfect fit, and yes they work beautifully! They're moderately priced and I couldn't imagine a better choice. The 18.1 gear ratio makes tuning quick and smooth. These locking tuners are a wise option that takes the time and frustration out of changing your strings too. These Grovers are groovy!
