What Are Locking Tuners? (And Do You Need Them?)

If you’ve ever finished stringing your guitar, played a few songs, and noticed your tuning drift again, even after stretching the strings, you have felt the frustration that locking tuners were designed to solve.

Locking tuners are one of the most common upgrades guitarists make to improve tuning stability and speed up string changes. They’re not new, but they are one of those small changes that can make a big difference in how your guitar performs.

This guide explains what they are, how they work, and whether they’re worth adding to your guitar.

What Are Locking Tuners?

Locking tuners look almost identical to standard tuning machines, but they have one key difference: a built-in locking mechanism that clamps the string in place.

Each tuner has a small knob or screw on the back (sometimes on the front). When you insert the string through the post, you tighten that knob, which locks the string down. Because the string is clamped, it doesn’t need to wrap several times around the post like a traditional tuner.

With the string secured, there is less slack, less slippage, and far fewer tuning issues.

How They Work

Traditional tuners rely on friction. You wrap the string around the post a few times and hope it stays tight. The problem is that friction can shift when you bend, strum aggressively, or use a tremolo arm.

Locking tuners solve this by mechanically gripping the string. Here is how it works:

1. Thread the string through the hole in the post.

2. Tighten the locking knob to clamp the string.

3. Tune up to pitch. No winding necessary.

Because the string is locked, there is no extra movement during playing. It is simple, clean, and effective.

🎸 The Benefits of Locking Tuners

1. Better Tuning Stability

With fewer wraps and a clamped string, your tuning holds up longer, even after heavy bending or tremolo use.

2. Faster String Changes

If you dread restringing, locking tuners are a game changer. You can swap all six strings in under five minutes. Pull the string tight, lock it, and tune up.

3. Less String Slippage

Since the string is physically secured, it will not slowly unwind or slip around the post over time.

4. Cleaner Headstock Look

Minimal winding means your strings stay neat and consistent across the headstock. It gives your guitar a clean, professional setup.

5. Perfect for Tremolo Systems

If you play a guitar with a tremolo, like a Strat or a Floyd Rose setup, locking tuners reduce tuning problems dramatically. They are a great match for floating bridges.

Are There Any Downsides?

There are not many, but here are a few things to consider:

• Cost: Locking tuners are more expensive than standard ones. A good set typically costs between $50 and $120.

• Weight: They are slightly heavier, which can affect the balance on lightweight guitars.

• Installation: Some guitars require drilling or enlarging holes in the headstock to fit them. This is a quick job for a guitar tech but worth checking before buying.

Other than that, they are one of the most worthwhile upgrades you can make.

Do You Need Locking Tuners?

If you perform live, record often, or change strings regularly, the answer is no you don’t need them. But you should want them!

Locking tuners make guitar maintenance faster and more reliable. They will not fix problems caused by a worn nut or bridge, but they make tuning stability far easier to manage.

If you mostly play at home and rarely change strings, they are a convenience upgrade rather than a necessity. Still, once you experience how quick and clean they are, it is hard to go back.

How to Install Locking Tuners

Installing locking tuners is straightforward, but you should always check your headstock hole size first.

Steps to install:

1. Remove the old tuners by loosening the screws and nuts that hold them in place.

2. Insert the new locking tuners through the headstock holes.

3. Secure them with screws and washers.

4. Thread the strings, tighten the lock, and tune to pitch.

Popular brands like Fender, Gotoh, Grover, and Hipshot make drop-in replacements for most guitars. Many modern Fenders and Squiers use a 10 mm hole size, while older vintage models might need adapter bushings.

If you are unsure, a tech can install them in about 15 minutes.

Locking Tuners vs. Standard Tuners

The difference might not seem huge on paper, but in practice it can be night and day for players who gig or record frequently.

Are They Worth It?

For most players, yes.

Locking tuners are one of the few upgrades that make a clear, immediate improvement to your playing experience. You will spend less time tuning and more time playing.

Combine them with a good set of strings, a solid cable, and a clean setup, and your guitar will feel noticeably more stable.
