Anyone aware of Robert Keeley’s knack for marrying timeless circuits to contemporary functionality knows the sense of anticipation when he decides to take on another classic. In the case of the pedals reviewed here, however, Keeley didn’t take on a single pedal. Instead, these three stomps from the new 4-in-1 Series each combine two classic circuits and then add the ability to use the clipping and EQ sections from each interchangeably. In many cases, these recombinations lead to untapped potential and unexpected sounds.
As a family, the Blues Disorder, Angry Orange, and Super Rodent (along with the Noble Screamer overdrive) have several features in common. All have drive, level, and tone controls with mini-toggles beneath the first and last of these. The pedals also allow the user’s choice of true bypass or buffered bypass operation, which can be switched on the fly with a two-second press of the footswitch. Each is built around a rugged printed circuit board and the pedals are all made in the U.S.
“The drive and tone mini-toggles mean you can choose the juicy, soft clipping and balanced response of the BB, or the hard clipping and midrange bump of the OC.”
Other basics shared throughout the line include a folded-metal enclosure measuring approximately 5" x 2.5" x 1.75", with jacks on the crown of the enclosure, and a standard center-negative power input for any 9-to-18-volt DC supply. I tested all three with a Fender Stratocaster and a Gibson ES-355, along with a tweed Deluxe-style 1x12 combo and a 65 Amps London head and 2x12 cab.
Blues Disorder Overdrive and Distortion
When Marshall released the BluesBreaker pedal back in 1991, which aimed at capturing the overdrive characteristics of its fabled Bluesbreaker amplifier, did they realize they were unveiling a classic in its own right? Few players thought it sounded much like a cranked mid-’60s JTM45 2x12 combo, but plenty of guitarists—John Mayer among them—dug its ability to slather succulent low-gain overdrive tone on a guitar signal. So, what happens if you combine this with another classic, the Fulltone OCD, and offer switching between the circuits or a hybrid mode? Voilà! The Blues Disorder.
Keeley isn’t the first to rethink these circuits. But his outside-the-box approach might make the pairing of the two more versatile than any rendition that has come before. The drive and tone mini-toggles mean you can choose the juicy, soft-clipping and balanced response of the BB, or the hard-clipping and midrange bump of the OC—and chain or double up on both. On the tone side, the BB position yields a transparent tone stage with simple high-frequency roll-off control, and the OC setting adds an active midrange boost with treble bleed from the knob. The brilliant part is you can mix one set of drive characteristics with the other’s tone stack.
The Blues Disorder quickly proved that the design premise is more than a novelty. The rich, warm overdrive of the BB side worked as an always-on tone sweetener or as a low- to medium-gain bump that can be tuned for blues, indie, or classic rock leads. That versatility is a big part of what made the BluesBreaker legendary in the first place. Set to dual OC, the heavier grind provides a canvas for harder-edged rhythm crunch and more in-your-face soloing.
The Verdict
The basic drive sounds here are arguably worth the price of entry. But the hybrid settings enable exponentially more shades of those original colors, many of which are dramatically different than the classic Marshall or Fulltone. I particularly liked the BB gain setting with the OC tone stage, which yielded rawer, throatier medium-gain OD. It’s important to note that output levels can change with switch changes. That inconvenience aside, I could barely find a bad sound in the Blues Disorder.
Angry Orange Distortion and Fuzz
The subjects of Keeley’s shotgun wedding on this occasion are the Sovtek “Civil War” Big Muff on the fuzz side and a ’78 Boss DS-1 on the distortion end. These two effects occupy very different segments of the drive spectrum. But Keeley points out that, while voiced differently, both the Big Muff and DS-1 employed very similar tilt control tone stacks, making them, in Keeley’s view, ripe for hybridization.
Both circuits rely on diode clipping to help generate distortion, but the MF uses soft-diode clipping where the DS mode switches to more jagged-sounding hard-diode clipping, which lends edgy aggression. The mini-toggle in the tone stage taps a slightly scooped-sounding profile in the MF position, then delivers a midrange push in the DS position. Of course, these stages can be mixed to apply one frequency curve to another style of clipping.
Just a few minutes with the Angry Orange offers a surprising lesson in how close these two iconic distortion tools can come to sounding like each other. Both modes excel at thick retro-metal riffs and lurching doomy power chords in their natural clipping and EQ pairings, and add sizzle and edge to lead lines. And though the tone shift between them is clear when you throw the drive switch from DS to MF, they transition quite seamlessly.
The Verdict
Switching to DS for drive and MF for tone tastefully broadens the frequency range of that signature Boss distortion, yielding thicker lows and more jagged highs. The flip side of that coin—the MF drive with DS tone—struck me as less versatile, yielding a very boxy, hollowed-out frequency range. Still, players that like to tinker with filtered fuzz sounds might find many tones to use here, and on the whole there’s a lot to love and explore in this classic fuzz-distortion fusion.
Super Rodent Overdrive and Distortion
Skeptics that view overdrives and distortions as variations on a few basic design riffs might look at the Super Rodent and ask, “Didn’t we already visit this flavor combo in the Blues Disorder?” We would counter that the Super Rodent proves there are many dirt circuits out there in the deep blue sea. And Keeley’s pairing of these unexpected bedfellows underscores that notion, delivering two more variations of hard and slightly less-hard filth via the mix-and-match tone and drive formula. The inspirations this time out are the Pro Co RAT Distortion and Boss SD-1 Super Overdrive, two very different gain pedals that combine here surprisingly well.
Though the basic design is consistent with other pedals in the 4-in-1 series, the combination of circuits here results in four very different and distinct voices, compared to those that we’ve heard so far. The RAT-style RT position of the drive switch accesses the heavier, more aggressive hard-clipping distortion in the pedal, while the SD setting yields a more tube-like, soft-clipping overdrive. Here, the tone switch changes things up significantly—from a basic, easily managed treble roll-off in the RT position to an active low-pass filter that provides rangier low and high end in SD mode.
To my ear, the Super Rodent proved the most successful of the hybridization efforts among the 4-in-1 pedals reviewed here. That observation is not meant to detract from the cool sounds the others achieve, but simply point out how well the Super Rodent expands the potential of these two circuits. Robert Keeley obviously knows his overdrive onions so it’s no surprise that the renditions of the classic RAT and SD-1 are so accurately achieved in their natural drive and tone switches. Flip the drive and tone settings against type in either direction, though, and the sonics expand dramatically.
The Verdict
Settling in quickly to the easy, juicy tone-thickening of the SD drive setting, I found myself totally seduced by this early Japanese overdrive circuit with the unique RAT tone stack grafted on. There’s a little more harmonic swirl in the midrange and a pillowy compression that makes things sound bigger and thicker overall, if a little less punchy. The result? A new overdrive classic that, to my knowledge, never existed. Conversely, mating the RT drive to the SD tone adds aggression, muscle, and bark to the fabled Pro Co sound. In every combination it’s great stuff!
Keeley Blues Disorder, Super Rodent & Angry Orange Demos | First Look
I love fuzz. I am so grateful for fuzz. I don’t know who or where I’d be—at least musically—without it. And whether or not you like using fuzz, you love fuzz, too. You just might not realize it. Fuzz pedals, which are considered loud, rowdy, and unnecessary musical devices by some tonal purists, have changed the world.
From Jimi Hendrix to Jack White, David Gilmour to Billy Corgan, fuzz pedals have not only shaped guitar sounds but shaped the way we think of and experience guitar. Starting in the 1960s, they have steered culture as the musical voice of protest (Hendrix’s “Machine Gun,” anyone?) and the communicator of a generation’s angst . And don’t forget the more recent doom and stoner genres! Also, some tones that you perceive as clean or merely overdriven are actually created by finding the sweet spot between a fuzz pedal and a guitar’s volume dial.
There are tons of different fuzz pedals out there right now, so navigating all of your options can seem like a difficult task. We truly live in the golden era of gear and, as a pedalhead, I’m here for it. But the roots of fuzz run deep to earlier eras. So in that spirit, here are some of my favorite modern fuzz boxes that nail the tones of yesteryear—without the vintage-market price tag. Enjoy! And keep thinking fuzzy!EarthQuaker Devices Hoof ($179 street)
The Hoof is a flagship pedal from this Akron, Ohio-based company, and for good reason. This pedal’s circuit is rooted in a specific tall-font Sovtek Big Muff owned by the Black Keys’ Dan Auerbach. According to Jamie Stillman, owner of EQD, Auerbach’s favorite Big Muff didn’t sound quite like other green Russian Big Muffs he’d played, so he approached Stillman to recreate its hairy goodness. The Hoof is a hybrid of germanium and silicon transistors—a modern variant of the Muff’s legendary, strictly silicon sound. While the original is a 3-knob fuzz (volume, tone, and distortion), the kicker here is a fourth “shift” control that allows you to dial in additional midrange to your liking. Want that doom-y wall of sound? It’s here. Need a bit more string articulation for your riffs? It can do that as well. Built tough, the Hoof is extremely easy to use to get killer vintage fuzz tones and will take a beating on the road.
Way Huge Swollen Pickle ($149 street)
Star designer Jeorge Tripps has had a huge impact in the pedal world for decades. The Swollen Pickle is one of the staples in his creative lineup. What started as a 3-dial Big Muff-style fuzz (See a pattern here?) took on a life of its own with the addition of “filter” and “scoop” controls. Between these two knobs, the sonic landscape is huge... you could even say way huge. The newest version of the Swollen Pickle features additional clipping options under the hood that allow you to tweak further, should you feel the need. But out of the box, this fuzz is a ripper capable of searing leads and wall-of-sound chords. Built like a tank, with a reasonable market price, I’m a big fan of this one. It’s great for guitarists interested in a Big Muff-rooted fuzz without committing to that voice exclusively. Definitely check it out!
Mythos Pedals Golden Fleece ($139 street)
Sometimes simple and stupid is the best approach, and it absolutely works with the Golden Fleece. This single-knob, no-nonsense fuzz from Zach Broyles’ company is a fine-tuned machine with a minimum of options. All the tough decision making has already been done and built into a germanium-and-silicon-based circuit. So, don’t let this pedal’s size and lack of additional controls scare you. It is a monster fuzz pedal.
With its single “more” knob (the output volume), touch dynamics, the pickup selection on the guitar, and guitar volume and tone settings play a huge role in the results. It cleans up extremely well and can go from light and crunchy to full-on saturated awesomeness. Tone-wise, it lives in a unique vintage-fuzz sweet spot. Muff-y? It kinda can be, but it has much more clarity and string definition. Fuzz Face-y? Yes, but it’s much smoother, while simultaneously more aggressive. You’d think a fuzz pedal with one knob would be easy to explain, but this pedal just does so dang much. I’m a huge fan of the tones that this stomp offers—especially at $139, and with the tiny amount of precious pedalboard real estate required. Mythos calls it, “your gateway pedal to fuzz.” Fair enough!
Analog Man Sun Face ($195 street)
What’s a list of killer vintage-sounding fuzzes without an Analog Man pedal? It’s no secret that Mike “Analog Man” Piera sits high up on the list of vintage-fuzz experts, and his constantly in-demand pedals (you’ve heard of the King of Tone?) are a direct result of his passion and knowledge of old-school dirt. I could write a whole article on his smartly crafted fuzz pedals alone. But the Sun Face, as the name might lead you to believe, is Analog Man’s take on the legendary Dallas Arbiter Fuzz Face—that little round box championed by guitar heavyweights like Hendrix, Stevie Ray Vaughan, Eric Johnson, and Pete Townshend. But Analog Man doesn’t just make a one-size-fits-all Fuzz Face clone. Piera offers a dozen different variations of the pedal, with a multitude of choices. Both silicon and germanium transistors are available, as well as low- and high-gain options, which are a result of Mike carefully hand-selecting transistors that allow us nerds to get very specific about what flavor of Fuzz Face sound we want in our rig. The Sun Face is a top-quality build from a top-quality builder. You really can’t go wrong with any variation if you’re chasing the vintage-fuzz dragon.
Red River Amplification Bonetender ($199 street)
The Bonetender was created out of a love for the classic MkII Tone Bender circuit, which Sola Sound debuted in 1966. This device has two knobs, three transistors (Russia-made NOS MP41A “flying saucer” transistors, for the super-nerdy), and a name that bears its influence on its sleeve. David Britton of Red River Amplification in Nashville has nailed the classic Tone Bender sound. He hand-picks his PNP germanium transistors to craft a warm, round voice, with insane sustain and exceptional clean-up. This straight-to-the-point 2-knob (dirt and volume) fuzz provides instant joy for players of all skill levels and is easily one of my favorite MkII-inspired fuzz pedals.
By the way, since you’ve seen the terms germanium and silicon come up in this article several times by now, I should probably give a quick explanation of what they are, for fuzz novices. Silicon and germanium transistors are semiconductors that amplify or alter electronic signals, like those produced by your guitar that travel through your cable. Silicon transistors are more modern, and were developed in the 1950s. Germanium transistors were developed in the 1940s, and opened the door to solid-state electronics. The earliest germanium fuzz pedal, the Maestro FZ-1 used by Keith Richards on “Satisfaction,” was introduced in 1962. The first silicon pedal appeared in the late '60s. Generally, silicon is less responsive to guitar volume attenuation but more temperature-stable than germanium, which can be fussy in hot or cold weather, but pedals using either germanium or silicon can blow a hole in the side of a barn. Okay?
ZVEX Fuzz Factory ($319 street)
Where to start with this one? Odds are you know about this pedal. It’s a staple on so many rigs. It has inspired thousands of guitar players, as well as other pedal builders. It has been loved and used by fuzz purveyors like Trent Reznor and Billy Gibbons. And it is a modern classic. It started as a Fuzz Face clone, but the Fuzz Factory quickly carved its own path in the pedal world, though it’s a bit divisive among players due to its chaotic nature. The Fuzz Factory, which debuted in 1995, was one of the first pedals that purposely use feedback-loop-style self-oscillation—something that other builders at the time tried to avoid. But this stomp’s self-oscillation can easily be tamed and is part of what makes it so damn versatile. The Fuzz Factory is perhaps one of the most flexible fuzz pedals ever created, capable of nearly any tone you’ve heard on classic records or sounds you hear in your mind. Ripping Velcro-style Jack White vibes, spikey “Satisfaction” leads, or full-blown wall-of-sound fuzz are all here! If you're not scared of fuzz pedals with more than three knobs, the five on this stomp (volume, gate, compression, drive, and stability) allow you to explore fuzz in new, creative ways.
Benson Amps Stonk Box ($279 street)
Chris Benson quickly went from unknown apprentice at Verellen Amplifiers and repair tech at Old Town Music in Portland, Oregon, to in-demand, consistently backordered boutique amp builder, and for good reason. Also, his contributions to the pedal world have been fantastic—specifically his creation of what he terms “automatic thermal bias technology.” Essentially, he invented a system that regulates and stabilizes the bias of germanium transistors in a pedal, no matter how hot or cold it is outside. This is a big deal! And the Stonk Box? It is a Tone Bender MkI-inspired device that excels in vintage fuzz voices, with tone, volume, filter, and trim controls. It nails the FZ-1, MkI, and Zonk Machine sounds (which are all basically the same thing). It does the sought-after, beautiful, blossoming fuzz sound. And it can surely handle your Keef riffs, but the range of this high-quality build goes well beyond that.
Rude Tech 3MuF-14 Distortion/Fuzz ($255 street)
Jesse Rhew, of Rude Tech in Nashville, really knocked this one out of the park. Taking three well-loved and legendary Sovtek Big Muff circuits—the "Civil War," "Green Russian," and "Black Russian"—and putting them in one enclosure is cool, right? But the modern improvements and additions included in the 3Muf-14 make these classic sounds more usable in any setting. If you’ve played a Big Muff-style circuit, you know it’s very common for your guitar or bass to lose presence as soon as you turn the Muff on in a live-band setting. Because of this, a lot of players run their Muff-style fuzzes into mid-heavy overdrives or EQs, so they don’t get lost in the mix. The 3MuF-14 adds a mid-focused drive circuit with its own footswitch, so your sweet riffs aren't left out of the fun. As you’ve gathered by now, there are lots of killer Big Muff-style circuits out there, but if you’re looking for a gig-able option that offers just enough tweak-ability without menu diving, the 3MuF-14—with volume, tone, and sustain dials, plus toggles for tone and Muff-style selection—should be on your watch list.
