JHS Pedals Packrat Distortion Review: The Ultimate Timeline of Rodent Tone

If you have spent any significant amount of time playing electric guitar, you have likely encountered the “Rat” circuit. Since its inception in the late 1970s, it has become one of the most recorded and worshipped distortion pedals in history. I remember my first experience with a vintage unit; the way it transformed a clean amp into a fire-breathing wall of sound was nothing short of transformative. However, as any gear head knows, the “Rat” isn’t just one pedal. It is a decades-long evolution of component changes, circuit tweaks, and rare boutique iterations. For years, I found myself buying, selling, and trading different versions—the “White Face,” the “Turbo,” the “You Dirty”—trying to find the one that fit my specific rig. The problem is that vintage units are often unreliable and prohibitively expensive, while modern reissues sometimes lack that specific “mojo” found in the originals. This is the exact problem that the JHS Pedals Packrat Distortion was designed to solve. Instead of forcing you to choose one era of distortion, it promises to put the entire history of the circuit into a single box. In this JHS Pedals Packrat Distortion Review, we will explore whether this ambitious pedal truly delivers on that promise or if it’s just another “jack of all trades, master of none.”

What to Consider Before Buying a Guitar Distortion & Overdrive Effects

A Guitar Distortion & Overdrive Effects is more than just an item; it’s a key solution for shaping your artistic identity and ensuring your guitar cuts through a dense mix. Whether you are playing in a bedroom or on a stadium stage, the way your gain is structured determines the emotional impact of your music. A high-quality distortion pedal solves the problem of “anemic” tone, providing the sustain, compression, and harmonic richness required for rock, metal, blues, and even jazz-fusion. Without the right dirt box, your solos can feel thin and your rhythm parts can disappear behind the drums and bass. Investing in a versatile tool like the JHS Pedals Packrat Distortion allows you to adapt to different musical environments without needing to overhaul your entire pedalboard every time you change genres.

The ideal customer for this type of product is someone facing the limitation of having a “one-trick pony” gain stage. If you are a session musician, a cover band guitarist, or a studio producer who needs a wide palette of gain textures, a multi-mode pedal is an essential investment. However, it might not be suitable for those who prefer the absolute simplicity of a one-knob “set and forget” pedal, or for those on an extremely tight budget who only need one specific sound. For those players, a dedicated single-circuit clone might be a more cost-effective choice, though they would miss out on the incredible versatility we found during our testing of the JHS Pedals Packrat Distortion.

Before investing, consider these crucial points in detail:

• Dimensions & Space: Pedalboard real estate is the most valuable currency for a modern guitarist. You need to consider whether a multi-functional pedal like the JHS Pedals Packrat Distortion saves you space by replacing three or four other pedals, or if its footprint (roughly 6 x 6 inches) is too large for your current setup. We found that the top-mounted jacks on many modern pedals help, but the JHS Pedals Packrat Distortion uses side-mounted jacks, so plan your patch cables accordingly.
• Capacity/Performance: In the world of distortion, performance is measured by headroom, noise floor, and touch sensitivity. You want a pedal that responds to your guitar’s volume knob. A high-performance pedal should be able to go from a light grit to a saturated fuzz-like distortion without becoming a muddy mess. The JHS Pedals Packrat Distortion is a masterclass in engineering because it maintains the specific performance characteristics of nine different circuits.
• Materials & Durability: Since these devices live on the floor and are literally stepped on, build quality is non-negotiable. Look for high-quality metal enclosures, sturdy potentiometers, and a reliable footswitch. Cheaper plastic pedals will inevitably fail under the rigors of touring. We’ve found JHS consistently uses top-tier components that can withstand years of heavy-footed use.
• Ease of Use & Maintenance: While having nine modes is great, it shouldn’t require a PhD to operate. The interface should be intuitive—ideally with familiar controls like Volume, Distortion, and Filter. Long-term maintenance usually involves keeping the jacks clean and ensuring you are using a high-quality, isolated power supply to prevent unwanted hum and protect the internal circuitry.

Once you understand these fundamental requirements, you can better appreciate how a premium unit like the JHS Pedals Packrat Distortion stacks up against the competition. It’s not just about making noise; it’s about having the right tool for the job.

While the JHS Pedals Packrat Distortion is an excellent choice, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

First Impressions: Unboxing the Legacy of the JHS Pedals Packrat Distortion

When the JHS Pedals Packrat Distortion first arrived at our studio, the first thing that struck us was the packaging. JHS has always had a knack for clean, minimalist aesthetics, and the JHS Pedals Packrat Distortion is no exception. It comes in a sturdy box that feels professional and intentional. Upon lifting the pedal out, the weight immediately signals quality. At 0.8 pounds, it feels substantial without being a brick. The matte black finish is iconic, paying homage to the original rodent-themed pedals that inspired it, but with a modern, refined touch. You can check the latest price and availability to see how this premium build fits into your gear budget.

Setting it up was a breeze. Despite having a complex “digital runway” system inside that manages 261 components, the external interface is refreshingly simple. There are no menus to dive into and no hidden shift functions. You have four knobs: Volume, Distortion, Filter, and the Mode selector. We were particularly impressed by the Mode selector’s “click.” It feels rugged and deliberate, ensuring you won’t accidentally bump it into the wrong setting mid-song. Compared to some of the digital modeling pedals we’ve tested, the JHS Pedals Packrat Distortion feels like a piece of high-end analog hardware. It doesn’t feel like a computer; it feels like an instrument. This initial tactile experience gave us high hopes for the sonic journey ahead.

Deep Dive Performance Analysis: The JHS Pedals Packrat Distortion in Action

The “Digital Runway” and Analog Integrity

One of the most impressive technical feats of the JHS Pedals Packrat Distortion is how it handles the switching between nine different circuits. Most “multi-voice” pedals use digital modeling to simulate the sounds of different gear. JHS took a completely different, and far more difficult, path. Inside the JHS Pedals Packrat Distortion, there are 261 individual physical components. When you turn the Mode knob, a digital controller (the “runway”) physically reroutes your analog signal through a specific combination of those components. This means that when you select the “OG” mode, you aren’t hearing a digital recreation; you are hearing your signal pass through the exact resistor and capacitor values found in a 1979 unit.

We spent hours A/B testing this against various standalone units. The transition between modes is seamless, and because the signal path remains fully analog, the “feel” is preserved. There is no latency, no digital artifacts, and no loss of dynamics. We found that the pedal responds beautifully to pick attack. If you dig in hard, the JHS Pedals Packrat Distortion barks with that classic aggressive mid-range. If you play softly, it cleans up just like a vintage piece of gear should. This level of engineering is why we believe it’s worth investing in the JHS Pedals Packrat Distortion if you value authentic analog tone above all else. It’s essentially a museum of distortion housed in a single pedalboard-friendly enclosure.

Sonic Versatility: From 1979 to the Boutique Era

The nine modes available on the JHS Pedals Packrat Distortion represent a curated history of the most important variations of this circuit. We started our testing with the “OG” mode, which replicates the early big-box versions. It has a raw, unrefined quality that is perfect for classic rock and punk. Moving to the “White Face” mode, we noticed a slightly more compressed and focused tone, which is the holy grail for many collectors. The “Turbo” mode was a personal favorite during high-gain testing; it uses LEDs for clipping, which results in more headroom and a much more aggressive, “crunchy” character that pushes a tube amp into glorious saturation.

But where the JHS Pedals Packrat Distortion really shines is in the rarer modes. The “LA” mode replicates the Ibanez Fat Cat, which has a smoother, more “amp-like” quality compared to the standard Rat. Then there’s the “Landgraff MO’D,” a boutique take on the circuit that usually costs hundreds of dollars on the used market. In this mode, the pedal becomes a sophisticated lead machine with incredible sustain and a harmonically rich top end. We also loved the “Caroline” mode, based on the Wave Cannon, which adds a unique mid-range character that helps you stand out in a loud mix. To experience every nuance of this legendary circuit, you really have to hear these modes side-by-side. The breadth of sounds available is staggering, making this a truly “desert island” pedal for any gain lover.

The Magic of the Filter Control

Any fan of the original rodent circuit knows that the secret sauce lies in the Filter knob. Unlike a standard “Tone” control that just cuts treble, the Filter on the JHS Pedals Packrat Distortion is a low-pass filter that works in reverse. Turning it clockwise cuts the highs, while turning it counter-clockwise opens it up. During our evaluation, we found that this control behaves slightly differently in each of the nine modes, just as it would on the original units. This is a level of detail that “clones” often get wrong. In the “Dirty” mode, the filter allows you to tame the massive low-end and fizz, turning the pedal into a sludge-metal powerhouse. In the “JHS” mode (the ninth setting), the filter feels more modern and wide-ranging, allowing for a higher-fidelity sound that works beautifully for modern worship or alternative rock.

We also noticed how the Filter interacts with the Distortion knob. At lower gain settings, the Filter can be used to add a “woody,” vintage warmth to your tone, almost acting like a dark overdrive. As you crank the Distortion, the Filter becomes essential for preventing the sound from becoming “ice-picky.” We found that the JHS Pedals Packrat Distortion manages to stay musical regardless of where the knobs are set. Even at extreme settings, it maintains its core identity. This is a testament to the component-matching JHS performed during development. You can explore the full range of legendary Rat tones by experimenting with these interactions yourself; it’s a very rewarding experience for any tone chaser.

Professional Reliability and Rig Integration

Beyond the sounds, a pedal at this price point needs to function perfectly in a professional rig. We tested the JHS Pedals Packrat Distortion with both single-coil and humbucker-equipped guitars, running into both clean Fender-style amps and high-gain British stacks. In every scenario, the pedal was remarkably quiet. High-gain distortion is inherently noisy, but the JHS Pedals Packrat Distortion has a very manageable noise floor, likely due to the high-quality internal power filtering. It runs on a standard 9V DC center-negative power supply and draws 100mA, which is well within the limits of most pedalboard power bricks.

We also appreciated the physical layout. While the jacks are side-mounted, which can be a minor inconvenience on tight boards, the overall size is compact enough to fit easily into most setups. The four-year warranty is one of the best in the industry, and it shows that JHS stands behind their craftsmanship. During our heavy testing, the pedal never stumbled, and the mode switching remained silent—no loud “pops” or clicks when changing settings. This reliability is why we recommend that serious players get the JHS Pedals Packrat Distortion for your pedalboard if you need a dependable workhorse that can handle the rigors of the road.

What Other Users Are Saying

The general sentiment surrounding the JHS Pedals Packrat Distortion is overwhelmingly positive, especially among tone enthusiasts who value variety. Many users echo our findings, stating that it has “quickly become one of my favorite overall dirt pedals.” One player noted that they were looking for a “more tweakable Rat” and found that this pedal provided far more than they expected. It is widely praised for its ability to cover everything from light crunch to fuzzy chaos. The inclusion of boutique modes like the Landgraff and Caroline Wave Cannon are frequently cited as the “standout” features that justify the higher price tag.

However, no product is without its critics. We found one user who felt the pedal sounded “generic” and another who reported a loose screw inside their unit upon arrival, suggesting a rare quality control slip or shipping damage. Some purists also argue that it doesn’t “fully nail” the exact sound of their specific vintage unit. This is an important point: vintage components often have “drift,” meaning two 1981 pedals can sound slightly different. JHS aimed for the “ideal” version of each circuit, which might differ slightly from a specific unit a user has owned for thirty years. Despite these minor subjective grievances, the consensus is that the JHS Pedals Packrat Distortion is a phenomenal engineering achievement and a must-have for fans of the circuit.

Top Alternatives to the JHS Pedals Packrat Distortion

1. JHS Pedals Morning Glory V4 Overdrive Pedal

The Morning Glory V4 is a very different beast than the JHS Pedals Packrat Distortion. While the Packrat focuses on aggressive, rodent-style distortion, the Morning Glory is a “transparent” overdrive based on the classic Bluesbreaker circuit. It is designed to add “grit” and “shine” to your tone without changing its core character. If you find the Packrat to be too aggressive or “fuzzy” for your needs, the Morning Glory is the perfect alternative. It excels at low-to-mid gain settings and is one of the best “always-on” pedals on the market. It’s a great choice for indie, blues, and church players who need a more subtle gain stage.

2. BOSS BD-2W Blues Driver Waza Craft

The BOSS BD-2W is a legendary workhorse that offers a different flavor of gain. This “Waza Craft” edition features a custom switch that provides a fatter, more modern response alongside the classic Blues Driver sound. While the JHS Pedals Packrat Distortion is a collection of nine different circuits, the BD-2W focuses on perfecting one specific sound. It has a more “dynamic” feel, behaving more like a tube amp’s preamp section. It’s an excellent choice for players who want a simple, bulletproof pedal that can go from a clean boost to a heavy overdrive. It’s also more affordable, making it a great alternative for those who don’t need the Packrat’s nine modes.

3. JHS Pedals 3 Series Compressor

While not a distortion pedal, we’ve found that the JHS 3 Series Compressor is an incredible companion to the JHS Pedals Packrat Distortion. If you love the high-gain modes of the Packrat but find they lack sustain or feel a bit “unruly,” a compressor at the beginning of your chain can tighten everything up. The 3 Series is simple, affordable, and effective. For players who are happy with their current distortion but want to “pro-up” their sound by adding sustain and leveling out their dynamics, this is a much better investment than another dirt pedal. It’s the “secret weapon” that makes your distortion sound like a professional studio recording.

The Final Verdict: Is the JHS Pedals Packrat Distortion the King of Dirt?

After weeks of rigorous testing and countless hours of playing, our conclusion is clear: the JHS Pedals Packrat Distortion is the most comprehensive tribute to the Rat circuit ever created. It isn’t just a distortion pedal; it’s a historical document that you can play.
