Top 10 Best Locking Tuners In 2020

Some guitar players would agree that the most vulnerable part of their instrument is the tuner. Touch anything here, tighten or loosen any knob, and your once-tight guitar is no longer in tune. These knobs are also prone to cracking under pressure, with some guitar tuners bending, warping, and breaking over time. How do you prevent these from happening and keep your guitar in perfect tune? The secret for some guitar players is the use of a device called a locking tuner. What it is and how it helps guitar players will be answered in this review.

What are Locking Tuners?

Locking tuners are basic yet brilliant technology. It works like a regular tuner, but inside of the eye of the tuner, there’s a little clamp that comes up as the tuner is tightened. This simple mechanism holds the string in the correct position and stops slipping in many ways. Guitar locking tuners will hold the string in place, and because of this will stop it from slipping. A locking tuner will keep your guitar tuned for a long period of time.

Benefits of Locking Tuners 

The obvious advantage of locking tuners is that you’ll get better tuning stability. However, there are some people who claim that it adds more weight to your headstock, and this weight (sometimes uneven weight) can severely affect the way you play.

If you don’t want a heavy neck, then don’t use locking tuners. Although the weight added will be very minimal. And no matter what may add a little bit of weight, it may not be not too much. There are also players who think that adding more weight on the headstock; some people feel that having more weight on the headstock creates a heavier or meatier tone.

And there is one thing that locking tuners are good at, and this is preventing slippage of the strings from the tuning peg. But take note that if your strings are out of tune, the tuners are not really at fault. There are many elements in a guitar that can affect tuning and stability. There’s a lot of different elements on a guitar that can contribute to poor tuning. This includes the entire body of the guitar from the bridge to the nut and even from the quality of the guitar strings.

Also, just because the string is secured by the tuner, it does not mean that you should stretch your strings. This is due to the fact that strings do stretch, and you want to make sure that the string is located securely between the nut, bridge, and all the other components and that the slack is balanced all over the strength of the neck and even along the entire length of the instrument.

The best practice is to stretch the strings like normal and then tune it back up again. Just because you are using a locking tuner does not mean the guitar will never go out of tune. You still need to calibrate your strings. Strings will go out of tune, and this can happen any time, and this is a natural thing, it’s just the way it happens.


Basically, the more things attached to the neck or anywhere on your guitar, things can possibly go wrong anytime. This is why most users don’t really find locking tuners necessarily. But if you like your guitar to stay in tune for many years and never to touch it, then a locking tuner may just be the one you need.

Finding the Right Set of Tuners for Your Guitar

Locking tuners are available in different brands and in many styles. There are locking tuners that are designed to meet the needs of particular guitars, and some provide the best fit. There are also locking tuners that require the user to drill the headstock for separate holes before these are installed on the instrument.

Therefore, if you’re looking for a locking tuner that will fit your type of guitar, shop wisely. Don’t shop on impulse and select the first bright and shiny thing that you find online. Consider the mechanism of the locking tuner and how this is applied to your instrument. Here are ten of the best locking tuners in the market today.
