Kluson Revolution Locking Diecast Tuners Review: The Ultimate Marriage of Vintage Aesthetics and Modern Precision
If you have ever stepped onto a stage under hot lights, or spent an afternoon in a humid rehearsal space, you know the sinking feeling of a G-string that simply won’t stay in pitch. For decades, guitarists—especially those of us wielding classic 3-per-side headstocks—have been forced to choose between the iconic “Keystone” look and the rock-solid reliability of modern hardware. You want the vintage vibe, but you need the stability of a 19:1 gear ratio. For years, I struggled with my 2014 Les Paul, constantly fighting the “ping” of strings catching in the nut or the gradual slip of older, lower-ratio machines. The frustration of stopping a session to retune every three songs is a creative killer. Failing to address tuning stability doesn’t just ruin your performance; it erodes your confidence in the instrument. That is exactly why I decided to test the Kluson Revolution Locking Diecast Tuners, seeking a solution that promised the best of both worlds without requiring me to drill new holes in a prized headstock.
- Featuring a locking mechanism to clamp and lock string into the tuner for improved tuning
- Includes mounting screws and headstock bushes (ferrules)
What to Consider Before Buying Electric Guitar Tuning Keys
Selecting the right tuning machines is more than just a cosmetic choice; it’s a fundamental upgrade to the mechanical integrity of your instrument. A high-quality set of Electric Guitar Tuning Keys is a key solution for inconsistent pitch, sluggish string changes, and the dreaded “backlash” where the tuner knob turns but the post doesn’t move. When you upgrade your tuners, you are essentially improving the resolution of your guitar’s “fine-tuning” capabilities.
The ideal customer for this type of product is someone facing stability issues on a Gibson-style headstock or a player who frequently changes strings and wants the speed of a locking mechanism. It’s perfect for the gigging professional who needs “set it and forget it” reliability. However, it might not be suitable for those who are strict “vintage purists” looking to maintain the lighter weight of pressed-steel Klusons, as these diecast models do add a bit of mass to the headstock. If you are extremely sensitive to “neck dive,” you should weigh the benefits of stability against the slight increase in weight.
Before investing, consider these crucial points in detail:
- Hole Diameter & Compatibility: Most modern guitars use a 25/64 inch (10mm) hole, while vintage-spec instruments use a smaller 11/32 inch hole. Before upgrading to the Kluson Revolution Locking Diecast Tuners, ensure your headstock is reamed for modern 10mm bushings, or be prepared to do some light modification.
- Gear Ratio: This determines how many times you turn the button to rotate the string post once. A 14:1 ratio is standard, but a 19:1 ratio—like the one found on the Kluson Revolution Locking Diecast Tuners—allows for much finer adjustments, making it significantly easier to hit that perfect pitch without overshooting.
- Materials & Durability: Look for diecast housings. Unlike older “stamped” metal tuners that can bend or leak lubricant, sealed diecast tuners are a single piece of solid metal. They protect the gears from dust and sweat, ensuring the “silky smooth” feel lasts for decades rather than years.
- Locking vs. Non-Locking: Locking tuners use a pin or clamp to hold the string in place. This eliminates the need for multiple “wraps” around the post. Fewer wraps mean less “string stretch” and fewer places for the string to slip, which is the primary cause of tuning instability during heavy bending or tremolo use.
Understanding these variables will help you decide if the Revolution series is the right fit for your specific playing style.

First Impressions: The Modern Soul of a Vintage Legend
When I first unboxed the Kluson Revolution Locking Diecast Tuners, I was immediately struck by the weight and the finish. These are not the flimsy, lightweight tuners of the 1950s. They have a substantial, premium feel that screams “engineering.” The nickel plating is flawless—deep, reflective, and professional. One thing I noticed right away, which was confirmed by other users, is that the pearloid buttons are a bit darker and more “marbled” than they appear in some stock photos. This is actually a plus; it gives them an aged, authentic look that blends perfectly with a nitrocellulose finish.
The assembly is straightforward. Kluson has cleverly kept the traditional two-screw mounting pattern. This means if you are coming from standard non-locking Klusons, these should drop right into your existing screw holes. Upon first turn, the 19:1 ratio is apparent; there is zero “slop” or backlash. You turn the knob, and the post responds instantly with a high degree of resistance that feels expensive. They feel like a high-performance engine hidden inside a classic car body.
Key Benefits
- 19:1 Gear Ratio provides incredible precision for fine-tuning.
- Drop-in compatibility for most Gibson-style two-screw mounting patterns.
- The rear-knob locking mechanism makes string changes 5x faster.
- Sealed diecast housing ensures lifetime lubrication and no mechanical backlash.
Drawbacks
- Heavier than vintage-style tuners, which may cause “neck dive” on very light guitars.
- String posts are shorter than standard, requiring a specific restringing technique.
A Deep Dive into the Kluson Revolution Locking Diecast Tuners’ Performance
Installation, Compatibility, and the 10mm Question
One of the most important aspects of any hardware upgrade is whether or not it actually fits without a trip to the luthier. In our testing, the Kluson Revolution Locking Diecast Tuners lived up to the “Revolution” name by being remarkably compatible with modern Gibson headstocks. I installed these on a Les Paul Standard, and the two-screw pattern lined up perfectly with the original holes. However, a point of expert advice: these require a 10mm (25/64 in.) peg hole. If you are trying to put these on a 1950s reissue that has the smaller vintage holes, you will need to ream the holes out.
We found that for guitars like the 2014 Melody Maker or the 2024 Les Paul Studio, these are a literal “drop-in” replacement. I was able to reuse my original mounting hardware in some cases, though the included bushings and screws are of high quality. One user mentioned using them on an 89 Sheraton and reported a “noticeable facelift.” This confirms my finding: these tuners are a versatile “bridge” between vintage aesthetics and modern specs. The ease of installation is a major selling point, provided you’ve confirmed your hole diameter beforehand. Seeing the sheer stability of these tuners once they are bolted down is a massive relief for any player who has dealt with wobbly, press-fit bushings in the past.
The 19:1 Gear Ratio: Surgical Precision
Most vintage tuners operate on a 12:1 or 14:1 ratio. While that was fine for 1958, modern players demand more control. The 19:1 ratio on the Kluson Revolution Locking Diecast Tuners is a game-changer. When I was tuning up to an open G for some slide work, I noticed I could make minute adjustments that simply weren’t possible with my old stock tuners. There is no “overshooting” the note. You don’t have to tune down and back up to “reset” the gear tension because the sealed diecast housing eliminates backlash entirely.
In practice, this means your guitar stays in tune longer because the gears are tightly meshed. I spent three hours recording aggressive bends and heavy vibrato, and the Kluson Revolution Locking Diecast Tuners didn’t budge. This level of precision is why professional techs often recommend these for studio guitars. When you are checking the current market value of high-end tuners, it is the gear ratio and internal tolerance that you are really paying for. These Klusons deliver a “silky” feel that rivals much more expensive boutique brands.
Restringing Speed and the Short Post Design
The locking mechanism on the back of these tuners is a traditional thumbwheel design. It is intuitive and robust. You simply thread the string through, tighten the wheel, and tune to pitch. No more “locking wraps” or winding the string around the post five times. We found that restringing an entire guitar took less than five minutes. This is a massive benefit for gigging musicians who might need to change a string mid-set.
However, we noticed a common observation among the community: the posts are shorter than original non-locking tuners. At 21.2mm, they sit lower to the headstock. Some might see this as a con, but as an expert, I see it as a mechanical advantage. Because you aren’t wrapping the string multiple times, you don’t need a long post. The shorter post actually creates a better “break angle” over the nut, which can help with sustain and reduce that annoying “pinging” sound of strings catching. I found the locking mechanism in action to be incredibly reliable; the pin clamps down firmly without shearing the string, which can sometimes happen with cheaper locking brands.
The Weight Trade-off: Stability vs. Neck Dive
It is important to be honest about the mass of these tuners. Because they are diecast and feature a locking pin and thumbwheel, they are heavier than the “Green Key” tuners found on vintage Gibsons. Each tuner weighs a bit more than its non-locking counterpart. On a heavy Les Paul, you won’t notice the difference. However, on a lightweight SG, this can contribute to “neck dive,” where the headstock wants to dip toward the floor when you let go of the neck.
One user mentioned a bit of “buyers remorse” regarding the weight, wondering if the non-locking version would have sufficed. From my perspective, the added stability and convenience of the locking feature far outweigh the extra ounce of weight. If you use a high-quality leather strap, the neck dive is negligible. The trade-off is a guitar that stays in tune through temperature changes and aggressive playing. When you see the nickel finish options and the classic pearloid buttons, it’s hard to argue that the aesthetic and functional upgrade isn’t worth the slight increase in mass.
What Other Users Are Saying
The general consensus among the guitar community is overwhelmingly positive, especially regarding the fit and finish. One owner of a 2014 Les Paul Melody Maker noted that they “fit perfectly” and that “string changing has become easier as you will not have to wind your strings.” This sentiment is echoed by almost everyone who has made the switch, emphasizing that the “upgrade is worth the money.”
However, the feedback isn’t without its nuances. A few users pointed out the shorter post height, with one mentioning they “tighten the button screws a tad bit more” for extra security. The most common “negative” feedback involves the weight. One reviewer cautioned that they might be “a little too heavy for weight-sensitive applications,” specifically mentioning the potential for neck dive on certain SG models. Despite this, the majority of users agree that the 19:1 ratio and the visual “facelift” given to the instrument make the Kluson Revolution Locking Diecast Tuners a top-tier choice for any Gibson owner. Many players who were previously skeptical of locking tuners on vintage-style guitars reported being “huge fans” after just one installation.
Comparing the Kluson Revolution Locking Diecast Tuners to Top Alternatives
If you aren’t quite sure if the Kluson look is right for you, or if you have a different headstock configuration, there are other world-class options to consider. Here is how the Kluson Revolution Locking Diecast Tuners compare to some of the industry’s other heavy hitters.
1. Hipshot Grip-Lock 6 Inline Locking Tuners with Universal Mounting Plate
- 6K1GL0CThese are genuine, factory-fresh Hipshot Grip-Lock tuners, for 6 In-line headstocks, with Hipshot buttons finished in Chrome and with full manufacturer warranty.
- These tuners have non-staggered posts, suitable for all 6-in line headstocks that tilt back, such as Strat or Tele.
The Hipshot Grip-Lock 6-inline system is the go-to for Fender-style guitars or any instrument with all six tuners on one side. The standout feature here is the Universal Mounting Plate (UMP), which allows you to install these without drilling a single screw hole into your headstock. While the Kluson Revolution Locking Diecast Tuners are designed specifically to match the vintage 3-per-side aesthetic, the Hipshot is all about modern utility. If you have a Stratocaster or a Telecaster, the Hipshot is likely the better choice, but for a Les Paul, the Kluson remains the king of style and fitment.
2. Hipshot 6GLO Locking Guitar Tuning Machines 3+3
- 3+3 headstock configuration
- Grip lock
This is the direct competitor to the Kluson Revolution Locking Diecast Tuners. The Hipshot 6GLO 3+3 also offers a locking mechanism and excellent stability. The main difference lies in the “industrial” look of the Hipshot versus the “vintage” look of the Kluson. The Hipshot uses an open-gear design which some players find visually striking, while others prefer the sealed housing of the Kluson for its protection against the elements. If you want a more modern, “techy” look for your guitar, the Hipshot is a fantastic alternative, but it won’t give you that classic Gibson silhouette that getting the best performance out of your Les Paul usually requires.
3. The String Butler V1 Stealth Guitar Tuning Upgrade
- The V1 String Butler mounts to the guitar by simply replacing your Truss Rod Cover with this part using the existing cover mounting point and screws.
- Addresses frustrating tuning issues found on many guitars with a 3 + 3 headstock configuration.
This is a completely different approach to the tuning problem. The String Butler is not a set of tuners; it is an add-on bracket that attaches to your headstock to correct the string pull angle. It is often used in conjunction with stock tuners to prevent strings from binding in the nut. While it’s a clever and effective tool, it doesn’t offer the 19:1 gear ratio or the fast string changes of the Kluson Revolution Locking Diecast Tuners. If your tuners are already high-quality but your strings are sticking at the nut, the String Butler is a great fix. However, for a total mechanical overhaul, the Kluson tuners are a much more comprehensive solution.
The Final Verdict: Are the Kluson Revolution Locking Diecast Tuners Worth It?
After putting the Kluson Revolution Locking Diecast Tuners through their paces, my conclusion is clear: these are arguably the best upgrade you can make for a modern 3-per-side guitar. They solve the two biggest headaches for any guitarist—tuning instability and slow string changes—all while maintaining the iconic look of a vintage instrument. The 19:1 gear ratio provides a level of control that stock tuners simply cannot match, and the build quality ensures these will likely outlast the guitar itself.
While the weight might be a concern for those with featherweight SGs, for the average player, the trade-off is more than fair. You are getting professional-grade hardware that looks like it belongs on a 1959 Burst. If you are tired of fighting your guitar to stay in pitch and want to spend more time playing and less time tuning, I cannot recommend these enough. They are a “pro-level” upgrade that is accessible to any player with a screwdriver. I highly recommend investing in the Kluson Revolution system today and finally giving your guitar the stability it deserves.
