Buyer’s Guide

What are locking tuners?

All standard guitars have machine heads that are used to secure the strings and keep the instrument in tune. The design of these tuners remained relatively unchanged for decades, until the early 80s when a number of manufacturers came out with a new type of locking a tuner that did not require that players wrap strings around the tuning post. Instead, these machines were designed with a special mechanism that effectively clams on to the string.

These new tuning machines were revolutionary – not only were string changes significantly faster, but tuning stability when using heavy amounts of tremolo (which was especially popular during the hair metal scene at the time) was vastly improved. When strings were still wrapped around tuning posts, they had a tendency to slip when the whammy bar was used for divebombs and the like, which very quickly put guitars out of tune. By having the string clamped in place, this problem instantly disappeared, and locking tuners became a runaway success.

What Are the Features To Look For?

When shopping for your locking tuners, make sure to consider these factors to ensure you buy the correct type for your guitar.

It’s important to understand that you need to buy tuning machines that correlate to the existing configuration of your headstock. If you have a 6-in-line setup like a Strat or a Tele, you will need to buy locking tuners that come designed for that setup. Similarly, if you have a 3×3 setup like a Les Paul, or an offset arrangement like 4×3 as found on many 7 string guitars, you should be looking to ensure that you’re buying a compatible set.

The next feature to look for is the size of the shaft hole. This varies between guitars,  and while there are options for installing bushings, or even routing out larger holes, if you buy a set with compatible dimensions you’ll save yourself the trouble of having to make permanent modifications to your guitar.

Lastly, look at the gear ratio. This figure represents how many turns of the knob it takes to turn the post through a full 360 degree rotation. For example, tuners with an 18:1 ratio require 18 full turns of the knob to turn the post through one rotation. The lower the first number in the ratio, the fewer turns are required. Lower numbers can make tuning faster, but they require much more precise movement of the tuning machine.


Fender Locking Tuning Machines –  Best Locking Tuners For Stratocasters

Fender Locking Tuners - Best Locking Tuners For Stratocasters
Fender Locking Tuners

Genuine Fender accessories specifically designed for the Stratocaster

These locking tuners from Fender are the gold standard when it comes to Stratocaster machine heads. They are a simple drop in solution for most American and Mexican Stratocasters, which will ensure the easiest possible installation and the best possible fit. The design is classic Fender, with a polished chrome finish, and standard Strat style knobs. On the back, the tuning caps have a satin finish with the iconic Fender ‘F’ logo – so not only are you getting a simple installation with these tuners, but you’re also keeping the look as close to the original design as is possible, which is something a lot of Strat players appreciate.

The locking mechanism is strong and simple to operate, and proves a huge tuning stability upgrade, even over American standard non-locking machines. They come with a staggered design, which helps to overcome the lack of break angle in the headstock, which is arguably only the biggest design flaws with Fender guitars. Having that improved break angle will benefit tone, playability, and also reduce the likelihood of strings breaking prematurely.

This set comes with all required mounting hardware, including bushings, tuner caps and screws. The gearing is set with a fairly standard 18:1 ratio which strikes a nice balance between tuning speed and precision. 

Verdict: These Fender locking tuners are very well made, and the chrome finish is amongst the best on the market. The 18:1 ratio makes tuning a breeze and the tuning stability is rock solid. Strat players won’t be disappointed with the looks, and they’ll definitely be impressed with the speed of string changes.

Classic stock looks with exceptional locking performance

If you didn’t look at the back of the headstock you’d swear you were seeing the stock vintage pearloid keystone tuners, that’s how faithful these Kluson Revolution series locking tuners are to the Gibson deluxe machines. They offer direct drop in replacement for the stock die cast tuners, using the standard 2 screw mounting patter. Installation is about as easy as it gets with these machines. They will fit Gibson guitars and Epiphones fitted with the deluxe style tuners – this also applies to SGs and ES models, too. The polished chrome finish looks great, and the knurled knob for the locking mechanism grips very well, even with sweaty hands.

The Keystone knobs are solid, and finished in a beautiful translucent pearloid, true to the originals. They come with a 19:1 ratio, so while tuning isn’t as fast as some other machine heads, getting it dialed in perfectly is actually very easy to do.

As you’d expect, this set does come with all required mounting hardware, so there’s no need to buy anything separately or try to reuse anything from your existing tuners. This set isn’t staggered, but thanks to the headstock break angle on Les Paul, SG, and ES guitars, it’s not necessary to stagger the tuners. 

Verdict: These Kluson Revolution Series tuners are as good as it gets when it comes to aftermarket Les Paul tuning machines. Their performance is fantastic, as evidenced by the precision tuning, and ease of string changes. Of course, all Les Pauls are at an advantage over guitars with tremolo arms when it comes to holding tune, but with these machines, you’re sure to notice even greater stability.

They offer all the style that comes with these fantastic looking vintage tuners, but with the benefits of modern locking machines. Tuning ratio is a lightning fast 15:1, making for the quickest string changes you’ve ever had.

This is not a staggered set, so you will need to keep your string tree(s) on the headstock, but the GBE machines are specially labeled as they have a smaller opening to assist with string security for the smaller unwound strings.

Their backs are made from hard wearing, stamped nickel, and the tuning knobs are solid and premium feeling, finished in a beautiful mirror chrome. No matter whether you play a genuine vintage instrument, a modern reproduction, or a newer series, these tuners absolutely complement the appearance of any Tele, and the tuning stability is night and day from standard machines.

Verdict: If looks are as important for you as performance, you can have both with these Gotoh vintage oval locking tuners.

High tech locking tuners to complement any shredding machine

These D’Addario AutoTrim tuning machines are the ultimate locking tuner for Ibanez guitars. They take string changing speed to the next level thanks to their patented Ned Steinberger designed string trimmer – once you’re at pitch, the tuner will cut off the excess string for you, saving you the extra step of trimming it yourself. They are purpose made for one thing – rock solid tuning stability under serious tremolo abuse. The black finish is pure rock and roll, these tuners definitely stand out from the chrome crowd.

They are equipped with an 18:1 worm gear, which strikes a great balance between stability and tuning precision. This is a 6 in line setup with 25/64” posts (10mm), so they should be compatible with most Ibanez guitars, as well as many other brands making Super Strat style guitars.

For increased visibility for string changes on stage, the posts are marked with a silver dot to aim your new strings at.

The ultimate locking tuners for extended range guitars

Timeless design and next generation tuning stability

While using locking tuners on an acoustic guitar isn’t exactly common, there’s no good reason why you shouldn’t make the upgrade. These Grover 502C Roto-Grip locking tuners are a fantastic way to preserve the classic look of your acoustic guitar whilst significantly improving its tuning stability and overall playability. They come in a 3×3 configuration, which is typical for most acoustic guitars. In some cases, they may even be a direct drop in replacement! If you play a Gibson or an Epiphone, there’s a good chance, especially on newer Epiphone models, that it came from the factory with Grover (or Grover pattern) tuners. If you want to switch them out for locking machines you won’t have too much work to do for installation. 

In classic Grover style, these tuners are made from steel and finished in mirror chrome. They are solid, and offer smooth, precise turning and an 18:1 ratio. Installation of new strings is straight forward – simply pull the new string through the post hole, give it one wrap, and then turn the read thumb screw to lock it down. Grover tuners are the go to for many high end manufacturers, so you know you are getting the best of the best.

Tuning stability with these machines, especially when installed on an acoustic guitar is peerless. Because there’s very little external influence like tremolo, once your strings are installed and locked down, they are going nowhere, which means you tune once, and stay there until it’s time to switch out the strings.

Verdict: Don’t discount locking tuners for acoustic guitars. Having that tuning stability upgrade is a huge difference maker, and of course, anybody who performs live will definitely enjoy the improvement in string change times should you happen to snap one while playing. These Grover Roto Grips are unquestionably the best locking tuners for any acoustic guitar!
