Locking tuners can be the best answer for guitarists that are tired of loosened strings, restringing, and going out of tune, as even the best guitar tuning pegs will eventually come loose sooner or later. The best locking tuners add tunning stability, make it easier to change strings, are not very heavy, and fit perfectly with your guitar without you needing to do any modifications unless you want to.

They shouldn't affect tone, they will help you avoid string slippage, and overall, they are fairly priced. When it comes to avoiding low-quality locking tuners, your only concern should be if it fits your guitar first. Some work best on certain guitars, such as Les Paul or even acoustic guitars. Before we reveal what the top choices are, and what makes or breaks them, let's see exactly what a locking tuner is and how does it work!

What are Locking Tuners?

Locking tuners are a guitar component or accessory, if you will, which looks and relatively acts exactly like the regular tuning pegs. They keep the strings from coming loose, keeping them in place, by holding the strings, rather than do so through friction and windings, as regular tuners do.

Their primary role is to help you stay in tune while also helping you in restringing your guitar faster. This is because locking tuners act differently than regular tuners. You push the string, rather than winding it, through the tuner and push the locking mechanism. You can wrap the string however you like now since the locking mechanism will hold it in place. Whereas with regular tuners, if you wind the string insufficiently, it will come to loosen, and you have to tune again.

Do Locking Tuners Affect Tone?

Contrary to popular belief, locking tuners do not affect tone. However, they do affect playability due to the increased weight on the headstock. This heavier feeling might make players alter their playing style a bit, and of course, their technique. Since the technique of the guitar player might change, the tone may do so as well, and this is why some believe that locking tuners affect tone, but they don't.

How Tight Should Locking Tuners Be?

There isn't a general rule on how tight locking tuners should be; however, it should feel comfortable. The bigger problem is when they are too tightened as they can lead to eventual degradation and damage. As a rule of thumb, tighten them very snug but not mashed.

How to String Locking Tuners?

Changing the strings on your guitar while using locking tuners is quite easy. Keep tension on the old string while you loosen the tuner, and take the string out by the back of the guitar. Take the new string and insert it through the tailpiece and pull it all the way through.

Pull the string with enough tension while also ensuring that it is aligned with the hole as it needs to go straight through the tuner. Now you have to tighten the locking tuner based on your needs and tune-up every new string. Clip every string about 1/8" from the hole.

Locking Tuners vs Traditional Tuners vs Locking Nuts

locking tuners vs traditional tuners

To understand how do locking tuners work, we also need to compare them to traditional tuners or the locking nut. As stated before, locking tuners are easy to install, give a boost in staying in tune, and their biggest advantage over traditional tuners is that the restringing time is greatly reduced and easier to do.

A locking tuner also appears to be better than a locking nut since a locking nut is designed to be locked, and thus the strings won't move as easily through the nut slots. A combination of the two is also not recommended.

Locking Tuners Buying Guide - Things to Consider

Now that you know how to use locking tuners, how they work, and what they do, it's time to mention a couple of important aspects before buying a set of tuners for your guitar that you should consider.

Guitar Design & Tuner Compatibility

Before buying a locking tuner, you should make sure it is compatible with your guitar. Otherwise, you won't be able to use them, or you will have to adjust the holes. For example, Gibson locking tuners come with three pegs since SG guitars have three pegs on both sides of their headstock.

Fender tuners may come in six-packs of pegs since a guitar like a Fender Telecaster has all six tuning pegs on one side. When buying locking tuners, check their configuration and layout, 3/3 or 3/6, and see if they fit with your guitar.

The best locking tuners for Les Paul, for example, come from Musiclily Pro. However, they won't fit on Strats and Teles. Some of the best acoustic guitar locking tuners also come from this brand, as their tuning machines worked quite well on them.

There is also the Musiclily Pro 6, full metal guitar locking tuners, which are designed specifically for Strat and Tele guitars. However, if metal is your thing, the best locking tuners for strat come from Fender.

Hole Size, Installation, and Drilling

Typically, guitars have these three standard string hole sizes: 13/32" - 10mm, 11/32" - 8.5mm, and 1/4" - 6mm. Not all tuners will fit with the peg holes on your guitar, and thus, you will need to drill and make them bigger. If you want high-quality work done on your guitar, you should take it to a specialist.

These machine heads should be easy to install. Just make sure you have tape to mask any unwanted sights, a drill 1.5mm, PH1 screwdriver, set square, and a 10mm spanner. You should also change your strings if you are trying out a new set of tuners, and choose if you want your locking tuner standard, vintage, for right-handed or left-handed usage.

Stability & Functionality

Locking tuners work very similarly to traditional tuners, and if you want truly accurate tuning, pitch, and stability, choose an 18:1 gear ration tuner configuration. The 18:1 gear ratio is the most popular out there. However, you also have a 16:1 tuning ratio and others variants.

Depending on your needs, choose the machine heads with the gear ratio best suited for you and your guitar. Tuning will be made easier nonetheless with these tuning machines. If you want to make your tuning even easier, check out grip lock locking tuners.

Durability

When it comes to durability, even these tuning machines wear off at some time. It all comes down to how well you take care of your guitars, tuning, and if the tuners are of great quality. How you handle these tuners will affect the outcome of how long they last, and before choosing them, take into consideration how often do you play.
