Discover Best Locking Tuners (2021) – Buyer’s Guide


Guitars feature a traditional tuner, am I right? So deciding to switch from the traditional version to the best locking tuners is quite a common response. But this transition requires an easy, quick headstock modification.

With that in mind, you might not like the notion of drilling holes in the guitar. So at such times, the only thing to remember is that locking tuners offer a major advantage over their traditional counterparts. What they do best is lock the strings in the right place. Therefore, eliminating intonation changes often accompanied with the loosening of the winding. Or when the string tends to slip!

But here’s the most significant benefit. Locking tuners speed up the changing of strings. You can lock in the new strings only by twisting the screw. So there’s no need to waste time in tying those strings. And frustration while doing so goes out the window too!

Top 10 Best Locking Tuners for Your Guitar!


If you’re serious about facilitating that switch from traditional to locking, you might love what lies ahead. The 10 models reviewed in the article are all popular choices suitable for professional playing. And they are, by far, the highest rated in the current music industry.

The most unfortunate news comes in the form of the “too tall” posts of the Fender Chrome Locking Tuners. If they were any shorter, you wouldn’t have to wind those strings as much to achieve the correct break angle. But it looks like you have to go through the trouble of doing just that.

Everything You Need To Know About the Best Locking Tuners

All the models discussed above perform so well that an improvement on the guitar is inevitable. Now, there’s nothing wrong with traditional tuners. Particularly if they’re of high quality! They are fine mechanisms. But it’s the locking tuners that make the string changing process much more convenient.

Better sustain, improved stability, and easier restrings; the three noteworthy benefits of using locking tuners. So let’s find out more about the difference between the two!

But first, here’s how to install locking tuners on any guitar:

Locking Tuners Anyone Can Install On Any Guitar.

Traditional Tuners vs. Locking Tuners

When the instrument just doesn’t agree to maintain the tune, does your technique or gear make any difference? The answer is NO, right? Not many guitarists talk about or discuss the importance of tuner models and styles. At least not as much as the other guitar components such as pickups, strings, and bridge. These parts are certainly crucial to the tone, but they don’t and won’t make any difference if the intonation is off.

This is where the best locking tuners come to the rescue. What they do is prevent the instrument from sounding off-tune. The strings naturally shift and stretch as per your finger movements. On top of that, environmental factors such as humidity and temperature don’t interfere with intonation.

Locking tuners drastically reduce the playing effects on the intonation. Translation: you don’t need to tune the guitar more frequently. Something that you normally do with the traditional version!

But here’s the thing, not many guitarists use locking tuners for the purpose of intonation. More often than not, they purchase the best locking tuners to bring more convenience to the table. When changing strings with the help of traditional tuners, you tighten the strings by tying them in a knot. But in the case of locking tuners, all you have to do is turn that tuning peg. The latter is a process that’s a lot more convenient and quicker.


So what’s the drawback of using locking tuners? The most notable disadvantage is the appearance factor. Since these parts feature a huge mechanism, they tend to look unsightly and bulky on the headstock. But you can always opt for aesthetically attractive looking versions. Like the ones reviewed in the article!

Even so, do you prefer the physical appearance of the tradition tuner? If yes, then you might not appreciate even the slim, attractive design of their locking counterpart.

Making a switch between the two requires some modification. There’s no denying that! But the good news here is that the modification is unobtrusive. Unlike the extensive modification of altering pickups or installing a bridge!

Choosing the Best Locking Tuners


When buying the best locking tuners, you have to take certain factors into account. For one, the tuner size plays a major role in the selection process.

There are models specifically designed for different guitars. It means they require that perfect fit. In that case, you might have to broaden the headstock hole. But if you somehow manage to get your hands on an exact set, you’ve hit the jackpot. Even if that’s not the case, making adjustments is no reason to not get locking tuners.

The next feature is tuner orientation. The staggered sets are suitable for guitars that have all tuners on one side of that headstock. Then come the 3X3 sets, which are an ideal pick for Les Paul type headstock designs.

Final Takeaway

My Choice: Fender Locking Tuners Chrome

Aftermarket tuners are affordable performance boosters. But, sometimes, they’re very crucial to the process. Guitars, no matter how expensive, are only as great as their key retention abilities. If they can’t match up to your rudimentary requirements, they’re of no good.

With that in place, a basic set of the best locking tuners has the capacity to deliver professional performance. And the most convincing part is that they are inexpensive, easy, and logical in the majority of cases. Especially the Fender Chrome Locking Tuners!

You’ll find this equipment on the company’s phenomenal American Deluxe guitar series. So you can easily use them on your locking tuner equipped Fender Telecaster or Stratocaster. But they work on other models as well. In that case, you’ll need to make slight, easy modifications.

The chrome plating is a feature responsible for strength and looks. So don’t expect the Fender Chrome Locking Tuners to not deliver reliable, consistent performance. With these magical tuners, you’ll spend most of your time and energy focusing on the sound. Instead of wasting time on intonation! Now that’s something, isn’t it!
