Kluson Plus Series 3 Per Side Tuning Machines Review: A Professional-Grade Precision Upgrade for Budget Guitars
We have all been there: you are mid-set, or perhaps just getting into the flow of a creative recording session, and suddenly your G-string is flat. Again. There is nothing that kills musical momentum faster than a guitar that refuses to stay in tune. For many players, especially those of us who enjoy the character of budget-friendly instruments like Epiphone Juniors or older Fender acoustics, the weak link is almost always the factory hardware. Cheap, “diagonal open-back” tuning machines or low-ratio trapezoid tuners are notorious for backlash—that annoying “dead zone” where you turn the knob and nothing happens. If you are struggling with a guitar that slips every time you perform a bend, it is time to stop blaming your technique and start looking at your hardware. We believe that upgrading to the Kluson Plus Series 3 Per Side Tuning Machines is one of the most cost-effective ways to transform a temperamental instrument into a reliable workhorse. If you’re tired of slipping pegs, you should see its full feature set and user reviews to understand how a simple hardware swap can change your playing experience.

- High Precision Tuning: 18:1 gear ratio provides smooth, precise tuning adjustments for better stability and reliability
What to Consider Before Buying Electric Guitar Tuning Keys
Electric Guitar Tuning Keys are more than just an item; it’s a key solution for the literal foundation of your instrument’s pitch. When you are looking to upgrade, you aren’t just buying metal pegs; you are investing in mechanical precision. A high-quality set of tuners ensures that the tension of your strings is held constant against the vibration of your playing and the environmental shifts in temperature and humidity. Without reliable tuners, even the most expensive guitar in the world will sound amateurish.
The ideal customer for this type of product is someone facing tuning instability on a mid-range or budget 3+3 headstock guitar, or a builder looking for a classic look with modern mechanical performance. It is particularly suited for those who want a “drop-in” replacement to avoid drilling new holes in their headstock. However, it might not be suitable for those who require locking tuners for extreme tremolo use or those with 6-in-line headstocks (like a standard Stratocaster). If you need ultra-high-end boutique locking capabilities, you might consider alternatives like Hipshot or D’Addario, though they often come at a much higher price point.
Before investing, consider these crucial points in detail:
- Dimensions & Space: You must measure your existing tuner holes and mounting screw locations. Most modern tuners require a 10mm (approx. 13/32″) hole. If your guitar has vintage-style 8mm holes, you will need to ream them out. Checking the “3+3” configuration—three on the left, three on the right—is essential for compatibility with Gibson and Epiphone style headstocks.
- Gear Ratio (Capacity/Performance): The gear ratio determines how many turns of the button equal one full turn of the string post. A 14:1 ratio is standard, but an 18:1 ratio, like that found in the Kluson Plus Series 3 Per Side Tuning Machines, allows for much finer adjustments. This is crucial for reaching that perfect pitch without “overshooting” it.
- Materials & Durability: Look for diecast housings and high-quality plating. Cheap tuners use “pot metal” that can strip or crack under the high tension of heavy gauge strings. Chrome or nickel plating should be thick enough to resist corrosion from the oils in your hands over years of use.
- Ease of Use & Maintenance: Consider whether the tuners are sealed or open-back. Sealed tuners, like these Klusons, come pre-lubricated and protected from dust and grime, meaning they require virtually zero maintenance over their lifespan. This “set it and forget it” nature is a massive benefit for gigging musicians.
In short, while tuners might seem like a simple mechanical part, the difference between a “good” set and a “bad” set is the difference between a guitar you love to play and one you want to throw across the room. Transitioning to a reputable brand ensures you are getting the engineering required for stage-ready stability.

First Impressions and Key Features: Unboxing the Kluson Plus Series 3 Per Side Tuning Machines
Upon unboxing the Kluson Plus Series 3 Per Side Tuning Machines, the first thing we noticed was the substantial weight and the mirror-like finish of the chrome plating. At 6.4 ounces for the set, they feel robust without being overly heavy, which helps prevent “neck dive” on lighter guitars like SGs. Unlike the flimsy, stamped-metal tuners found on many entry-level instruments, these feature a solid diecast housing that screams durability. The set comes complete with everything you need: the six tuning machines, six press-fit bushings, and the necessary mounting screws. This completeness is a feature that really sets it apart from cheaper alternatives that often force you to reuse old, worn-out hardware. To ensure you’re getting the genuine article with all its included accessories, it’s worth it to check the latest price and availability before you start your next guitar project.

A Deep Dive into the Performance of the Kluson Plus Series 3 Per Side Tuning Machines
The Installation Experience: A True “Drop-In” Solution?
One of the biggest anxieties for any guitar owner is the prospect of drilling into their instrument. We approached the installation of the Kluson Plus Series 3 Per Side Tuning Machines with a critical eye, testing them on several popular models. On an Epiphone SG, these were a dream. The existing holes lined up perfectly, and the press-fit bushings snugged into place with just the right amount of resistance. We found that for guitars equipped with those cheap, factory diagonal open-back tuners, these are the ultimate upgrade. As one user we spoke with noted, they were a “perfect drop-in” for a Fender CC60-S, providing an immediate professional feel to a budget acoustic.
However, “drop-in” is a relative term in the guitar world. While the 10mm diameter is standard for modern headstocks, some older or entry-level models—like certain Epiphone Junior variants—might have slightly different screw hole patterns. During our testing, we found that even if you have to drill a small pilot hole for the mounting screw, the diecast housing of the Kluson Plus Series 3 Per Side Tuning Machines is large enough to cover the old holes, keeping the aesthetics clean. Once you pick up a set for your own build, you’ll see how much more substantial they feel compared to stock hardware. The precision of the round head press-fit bushings ensures that the string post is centered and stable, which is the first step toward eliminating tuning creep.
Mechanical Precision: The 18:1 Gear Ratio Advantage
The “heart” of any tuning machine is the internal gearing. Most standard tuners use a 14:1 ratio, which is functional but can feel “jumpy.” The Kluson Plus Series 3 Per Side Tuning Machines utilize an 18:1 ratio, and the difference is palpable. In our hands-on testing, this higher ratio allowed us to “creep up” on the note with microscopic precision. This is particularly important for the plain G and B strings, which are notoriously difficult to intonate perfectly. When you turn the button, the response is immediate and linear; there is no slipping and no sudden jumps in pitch.
We did notice that some units felt “stiff” right out of the packaging. We found that this is often due to the factory grease being a bit thick or the tension screw on the button being tightened down for shipping. A half-turn of the button screw usually solves this, resulting in a buttery-smooth action. This level of precision is why many choose these Kluson tuners over stock options; it transforms the act of tuning from a chore into a quick, effortless adjustment. While one user reported a “dead zone” in their batch, our expert evaluation of multiple sets suggests this is a rare defect rather than a design flaw. The gear engagement is generally tight, minimizing the backlash that plagues cheaper cast-housing tuners.
Tuning Stability and Long-Term Reliability
Stability is the ultimate metric for any tuner review. We put the Kluson Plus Series 3 Per Side Tuning Machines through the wringer, performing aggressive multi-step bends and heavy rhythmic strumming. The result? The strings held their pitch remarkably well. The diecast housing plays a huge role here. Because the gears are fully enclosed, they are protected from environmental debris and the internal lubrication stays where it belongs. This creates a consistent friction level that resists the “slipping” caused by string tension pulling against the post.
We also analyzed how these tuners handle different string gauges. Even with a heavy .012-.054 set, the Kluson Plus Series 3 Per Side Tuning Machines didn’t flinch. The metal used in the worm gear and string post is hard enough to resist the “grooving” that can happen over time with softer metals. For players who gig frequently in humid environments or under hot stage lights, the sealed nature of these tuners is a lifesaver. You won’t have to worry about the gears seizing up or becoming “gritty” over time. This consistent performance is why we consider them a top-tier upgrade for any 3+3 headstock guitar.
Aesthetics and Build Quality: Modern Performance, Classic Look
Kluson is a name synonymous with guitar history, and the Kluson Plus Series 3 Per Side Tuning Machines manage to honor that heritage while providing modern performance. The chrome finish is deep and flawless, reflecting the quality you’d expect from a brand that has been a staple in the industry for decades. The knobs are ergonomically shaped, providing a good grip even if your fingers are a bit sweaty during a long session. They look right at home on a classic Les Paul-style guitar, but they also modernize the look of more contemporary designs.
We appreciated the attention to detail in the mounting hardware. The screws are made of a hardened alloy that doesn’t “round out” or snap off—a common frustration with the cheap screws included with “no-name” tuner sets. Everything about this product feels intentional. When you look at your headstock and see the Kluson name, there is a psychological sense of security that comes with knowing your instrument is equipped with professional hardware. It’s an investment in both the sound and the soul of your guitar. If you’re looking for that perfect balance of style and substance, we highly recommend you grab these tuning machines today.
What Other Users Are Saying
The general consensus among the guitar community is that the Kluson Plus Series 3 Per Side Tuning Machines offer a significant ROI (Return on Investment). Most users celebrate how these tuners “keep it in tune and ready to rock,” especially when used to upgrade entry-level instruments. One owner mentioned they were “really good drop-ins for my Epiphone SG,” noting better stability and smoother turning than the stock units. Another user highlighted their value as an “excellent replacement for factory diagonal open-back machines,” which are a common pain point on many mid-budget acoustics.
On the flip side, some users have noted that while the fit is usually excellent, you should always “verify your measurements before buying.” A small minority reported that the buttons can be “a little hard to turn,” which aligns with our findings regarding factory tension settings. There was also one report of a “bad batch” where the shaft took multiple turns to engage, but this appears to be an outlier. Overall, the feedback confirms our expert assessment: these are high-quality, reliable tuners that solve the most common tuning problems faced by average players.
Comparing the Kluson Plus Series 3 Per Side Tuning Machines to Top Alternatives
1. Guyker 6 In-line Locking Guitar Tuners
- Package includes: 6 pieces (6 for right hand) lock guitar tuners pegs, mounting hardware (screws, bushings and washers) included. Good replacement for almost electric, folk or acoustic guitars.
- Precision 1:18 gear ratio with sealed lubrication, cast housings and metal knobs.
While the Kluson units we reviewed are a 3+3 configuration, the Guyker 6 In-line Locking Guitar Tuners are the go-to for Fender-style headstocks. These offer a 1:18 ratio similar to the Kluson, but with the added benefit of a locking mechanism. Locking tuners make string changes significantly faster and can offer even more stability for players who use a tremolo bar. However, if you have a Gibson or Epiphone style guitar, these won’t fit your headstock. They are a fantastic budget alternative for S-style guitars, but they lack the heritage and specific “drop-in” compatibility that the Kluson Plus Series 3 Per Side Tuning Machines provide for 3+3 headstocks.
2. Hipshot 6GLO Locking Guitar Tuning Machines 3+3
- 3+3 headstock configuration
- Grip lock
The Hipshot 6GLO Grip-Lock tuners are a premium step up from the Kluson Plus Series. Their “Universal Mounting Plate” (UMP) is a revolutionary feature that allows you to install them on almost any guitar without drilling a single screw hole. They are incredibly stable and feature a very high-quality locking knob. Who should buy these instead? Players with high-value vintage instruments who are terrified of drilling and those who want the absolute best locking performance available. They are considerably more expensive than the Kluson Plus Series, making the Klusons the better choice for players looking for the best “bang for their buck” on a mid-range guitar.
3. D’Addario Locking Tuners for Guitars
- AUTOMATICALLY CUTS EXCESS STRING WHILE TUNING: Trims excess string while tuning to ensure consistent and accurate tuning.
- EASY STRING CHANGES: The locking tuners make changing strings fast and easy.
The D’Addario Auto-Trim tuners are unique because they actually cut the excess string as you tune up, eliminating the need for wire cutters. They are a 6-in-line setup (though 3+3 versions exist), making them a competitor more in terms of brand prestige than direct fit for this specific Kluson model. They offer great stability and a sleek, modern look. However, they are quite heavy and the “auto-trim” feature can be hit-or-miss with very thin high-E strings. If you value convenience and a modern aesthetic, D’Addario is a strong contender, but for a classic look and dependable, straightforward 18:1 precision, the Kluson Plus Series 3 Per Side Tuning Machines remain our top recommendation for most 3+3 headstock upgrades.
Final Verdict: Are the Kluson Plus Series 3 Per Side Tuning Machines Worth It?
After extensive testing and comparison, our verdict is clear: the Kluson Plus Series 3 Per Side Tuning Machines are an exceptional upgrade for any guitarist struggling with tuning instability. They successfully bridge the gap between “budget” hardware and high-end boutique components. The 18:1 gear ratio is the star of the show, providing a level of precision that stock tuners simply cannot match. While there may be occasional stiff buttons or the need for minor pilot holes on certain guitar models, the overall improvement in tuning stability and the professional feel of the chrome-plated diecast housing make them a “no-brainer” investment.
We recommend these tuners to any Epiphone, budget Gibson, or acoustic guitar owner who wants to stop fighting their instrument and start enjoying the music. They offer the perfect blend of vintage Kluson aesthetics and modern mechanical reliability. If you are ready to give your guitar the precision it deserves and finally put an end to those mid-song tuning sessions, we highly recommend you grab these tuning machines today and experience the difference for yourself.
