Locking Tuners for PRS SE Custom: The Complete Guide

If you own a PRS SE Custom guitar, you might be considering upgrading your tuners to locking tuners. This is a popular and effective modification that can enhance tuning stability, improve string changes, and take your playing experience to the next level. But how exactly do locking tuners work for a PRS SE Custom? What should you look out for, and are there real benefits? Let’s break it all down and guide you through every aspect of this upgrade.


Why Upgrade to Locking Tuners on Your PRS SE Custom?

Locking tuners are designed to clamp down on the string at the post, preventing slipping and making the tuning process more reliable. Here are the main reasons guitarists choose to install them on their PRS SE Custom:

  • Improved Tuning Stability: Locking tuners keep your guitar in tune longer, especially during aggressive playing or extensive bending.
  • Faster String Changes: The lock mechanism means you don’t have to wind strings as much, making string changes quick and hassle-free.
  • Ideal for Tremolo Users: If you use the tremolo arm, locking tuners greatly reduce detuning.
  • Enhanced Performance: Whether playing live or recording, less time tuning means more time playing.

Understanding PRS SE Locking Tuners: What Makes Them Special?

Not all locking tuners are the same, especially regarding fit, feel, and function on a PRS SE Custom:

  • Direct Fit: PRS SE locking tuners are manufactured to fit directly into SE Custom models without modification.
  • 3+3 Configuration: SE Customs have six tuners arranged in a 3-per-side (3+3) headstock layout.
  • Quality Materials: PRS-branded tuners are known for their solid construction and smooth operation.
  • Aesthetic Match: Factory replacements maintain the classic PRS look with chrome or black options.

Step-by-Step: Installing Locking Tuners on Your PRS SE Custom

Upgrading to locking tuners is straightforward, but following the right steps ensures a smooth installation. Here’s how you can do it:

1. Gather Your Tools and Parts

  • New locking tuners set (preferably PRS SE-specific)
  • Phillips-head screwdriver
  • String winder (optional but helpful)
  • Small socket or wrench (for tuner nuts, if needed)
  • Clean, flat workspace

2. Remove the Existing Tuners

  1. Loosen and remove all strings from your guitar.
  2. Using your screwdriver, carefully unscrew and remove each stock tuner from the headstock.
  3. Keep the screws safe; some replacement tuners use the same screws.

3. Prepare and Test-Fit the New Tuners

  • Dry fit a locking tuner into one of the tuner holes to ensure sizing matches.
  • On PRS SE Customs, reputable locking tuners usually fit perfectly.
  • If the fit is tight, don’t force—most issues arise from aftermarket, non-PRS tuners.

4. Install the New Locking Tuners

  1. Slowly insert each tuner into the headstock.
  2. Position it so the tuner lines up with the existing holes.
  3. Insert and gently tighten screws. Do not overtighten.
  4. Use the nut or washer provided to secure the tuner posts, if present.

5. Re-string and Test

  • Install new strings following the locking tuner workflow: insert the string, clamp it by turning the mechanism, and tune to pitch.
  • Test the tuning stability and make sure each tuner turns smoothly.

Benefits of Locking Tuners on the PRS SE Custom

Locking tuners are popular for a reason. Here’s what you’ll notice after the install:

  • No More String Slipping: The clamping mechanism means your strings are held securely.
  • Stable Pitch: Stay in tune longer, even with big bends and heavy strumming.
  • Reduced String Breakage: Less winding around the post means less friction and fewer string kinks.
  • Professional Feel: Many guitarists report a “premium” feel after upgrading.

Potential Challenges When Upgrading

While the process is usually smooth, there are a few things to be mindful of:

  • Compatibility Issues: Some non-PRS tuners may not align perfectly with your PRS SE Custom’s mounting holes or shaft diameter.
  • Installation Caution: Overtightening screws or nuts can damage the headstock.
  • Aesthetic Differences: Not all aftermarket tuners visually match PRS’s elegant headstock style.

Tip: Many PRS SE Custom owners opt for the official PRS SE locking tuners, as they deliver a guaranteed fit, streamlined installation, and the look matches perfectly.


Practical Tips & Best Practices

When upgrading, keep these in mind:

  • Keep the Old Tuners: Store your original tuners in a safe place. If you ever sell the guitar or want to return it to stock, you’ll have them.
  • Consider Tuner Gear Ratios: Gear ratio affects tuning precision. PRS locking tuners typically offer smooth, precise adjustment—confirm before buying others.
  • Install One at a Time: If you’re new to this, swap tuners one by one to maintain orientation and avoid confusion.
  • Clean the Headstock: Take this chance to clean the tuner area, often missed during regular maintenance.
  • Ask for Help: If you feel unsure, local guitar shops can usually install tuners for a modest fee.

Cost Tips: Saving Money on Locking Tuners

Price can vary, especially with shipping and import fees:

  • Shop Around: Compare prices at multiple retailers—some big-box and online stores offer periodic sales or bundles.
  • Official vs. Aftermarket: While official PRS tuners may cost more, they often save time and hassle by fitting perfectly.
  • Consider Shipping: Factor in shipping costs, especially if ordering internationally. Some music shops offer free shipping over certain amounts—wait for such offers.
  • Local Dealers: Buying locally can save on shipping and ensure returns or exchanges are easier.

What to Expect After the Upgrade

Often, the benefits are immediate and obvious:

  • Tuning Holds Strong: After a stretch period, tuning is rock solid.
  • Faster Setup: String changes can take half the time, perfect for gigging or recording.
  • Peace of Mind: You’ll spend less time worrying about tuning or string issues.

Many players also notice improvements in guitar confidence—knowing your guitar is stable and ready to play is a huge boost.


Frequently Asked Questions (FAQs)

Can I install locking tuners on my PRS SE Custom by myself, or should I get a tech to do it?

If you are comfortable using basic hand tools and following instructions carefully, installation is generally straightforward and can be done at home. However, if you are concerned about damaging your instrument or encounter compatibility issues, a professional guitar tech or luthier can ensure a flawless installation.

Will any locking tuners fit my PRS SE Custom, or do I need model-specific ones?

While some aftermarket brands make universal-fit tuners, it’s strongly recommended to use locking tuners designed for PRS SE guitars, as they guarantee direct fit and matching aesthetics. Other brands may require minor drilling or not fit at all.

Do locking tuners actually keep my guitar in tune better?

Yes. Locking tuners minimize string slippage and make tuning more stable, especially after bending strings, using a tremolo, or playing aggressively. They’re not a cure-all for tuning issues, but they’re one of the best upgrades for stability.

Is there a difference in tone or sustain after installing locking tuners?

Most players do not notice any significant change in tone or sustain after installing locking tuners. The primary benefits are tuning stability and convenience. Any tonal differences are negligible.

How much do PRS SE locking tuners usually cost, and are they worth it?

Prices vary but are typically in the range of $70-$110 for a full set. They’re considered a worthwhile investment for most players, given the convenience, performance improvement, and enhanced tuning stability they deliver.


In Summary

Upgrading your PRS SE Custom to locking tuners is one of the simplest, most effective, and rewarding modifications you can make. With improved tuning stability, quicker string changes, and hassle-free installation (especially with PRS-sepcific models), it’s a no-brainer for most players. Keep compatibility in mind, use careful installation techniques, and don’t forget to enjoy the new freedom that locking tuners bring to your music-making journey!
