UAFX Enigmatic ’82 Overdrive Special
uaudio.com
I’ve never played a realDumble. I’d venture most of us haven’t. But given my experiences with James Santiago’s UAFX modeling pedals, most recently theUAFX Lion, I plugged in the new Dumble-inspired UAFX Enigmatic confident I’d taste at least the essence of that very rare elixir. You could argue there is no definitive Dumble sound. Each was customized to some extent for the customer, and they are renowned nearly as much for dynamic responsiveness and flexibility as their singing, complex, clean-to-dirty palettes.
The Enigmatic nails the flexibility, for sure. To my ears, its tone foundation lives somewhere on a sliver of Venn diagram where a black-panel Fender and a 50-watt Hiwatt intersect. It’s alive, dimensional, snappy, sparkly, massive, and, at the right EQ settings, hot and excitable. But the Enigmatic’s powerful EQ and gain controls, multiple virtual cab and mic pairings, rock, jazz, and custom voices, plus additional deep, bright, and presence controls enable you to travel many leagues from that fundamental tone. The customization work you can do in the app enables significant changes in the Enigmatic’s tone profile and responsiveness, too. All these observations are made tracking the Enigmatic straight to a DAW—making the breadth of its personality even more impressive. But the Enigmatic sounds every bit as lively at the front end of an amp, and black-panel Fenders are a primo pairing for its saturation and sparkly attributes. The Enigmatic is nearly $400, which is an investment. But considering the ground I covered in just a few days with it, and the quality and variety of sounds I could conjure with the unit just sitting on my desk, the performance-to-price ratio struck me as very favorable indeed.

Cosmodio Gravity Well
cosmod.io
Know what a wavefolder does to your guitar signal? If you don’t, that’s okay. I didn’t either until I started messing around with the all-analog Cosmodio Instruments Gravity Well. It’s a dual-effect pedal with a tremolo and wavefolder, the latter more widely used in synthesis that , at a certain threshold, shifts or inverts the direction the wave is traveling—in essence, folding it upon itself. Used together here, they make up what Cosmodio calls a sonic refractor.
Two Plus One
Gravity Well’s design and control set make it a charm to use. Two footswitches engage tremolo and wavefolder independently, and one of three toggle switches swaps the order of the effects. The two 3-way switches toggle different tone and voice options, from darker and thicker to brighter and more aggressive. (Mixing and matching with these two toggles yields great results).
The wavefolder, which has an all-analog signal path bit a digitally controlled LFO, is controlled by knobs for both gain and volume, which provide enormous dynamic range. The LFO tremolo gets three knobs: speed, depth, and waveform. The first two are self-explanatory, but the latter offers switching between eight different tremolo waveforms. You’ll find standard sawtooth, triangle, square, and sine waves, but Cosmodio also included some wacko shapes: asymmetric swoop, ramp, sample and hold, and random. These weirder forms force truly weird relationships with the pedal, forcing your playing into increasingly unpredictable and bizarre territories.
This is all housed in a trippy, beautifully decorated Hammond 1590BB-sized enclosure, with in/out, expression pedal, and power jacks. I had concerns about the durability of the expression jack because it’s not sealed to its opening with an outer nut and washer, making it feel more susceptible to damage if a cable gets stepped on or jostled near the connection, as well as from moisture. After a look at the interior, though, the build seems sturdy as any I’ve seen.
Splatterhouse Audio
Cosmodio’s claim that the refractor is a “first-of-its-kind” modulation effect is pretty grand, but they have a point in that the wavefolder is rare-ish in the guitar domain and pairing it with tremolo creates some pretty foreign sounds. Barton McGuire, the Massachusetts-based builder behind Cosmodio, released a few videos that demonstrate, visually, how a wavefolder impacts your guitar’s signal—I highly suggest checking them out to understand some of the principles behind the effect (and to see an ’80s Muppet Babies-branded keyboard in action).
By folding a waveform back on itself, rather than clipping it as a conventional distortion would, the wavefolder section produces colliding, reflecting overtones and harmonics. The resulting distortion is unique: It can sound lo-fi and broken in the low- to mid-gain range, or synthy and extraterrestrial when the gain is dimed. Add in the tremolo, and you’ve got a lot of sonic variables to play with.
Used independently, the tremolo effect is great, but the wavefolder is where the real fun is. With the gain at 12 o’clock, it mimics a vintage 1x10 tube amp cranked to the breaking point by a splatty germanium OD. A soft touch cleans up the signal really nicely, while maintaining the weirdness the wavefolder imparts to its signal. With forceful pick strokes at high gain, it functions like a unique fuzz-distortion hybrid with bizarre alien artifacts punching through the synthy goop.
One forum commenter suggested that the Gravity Well effect is often in charge as much the guitar itself, and that’s spot on at the pedal’s extremes. Whatever you expect from your usual playing techniques tends to go out the window —generating instead crumbling, sputtering bursts of blubbering sound. Learning to respond to the pedal in these environments can redefine the guitar as an instrument, and that’s a big part of Gravity Well’s magic.
The Verdict
Gravity Well is the most fun I’ve had with a modulation pedal in a while. It strikes a brilliant balance between adventurous and useful, with a broad range of LFO modulations and a totally excellent oddball distortion. The combination of the two effects yields some of the coolest sounds I’ve heard from an electric guitar, and at $279, it’s a very reasonably priced journey to deeply inspiring corners you probably never expected your 6-string (or bass, or drums, or Muppet Babies Casio EP-10) to lead you to.

McGregor Pedals Classic Fuzz
mcgregorpedals.com
Compared to the dynamic germanium Fuzz Face, silicon versions sometimes come off as brutish. And even though they can be sonorously vicious, if dirty-to-clean range and sensitivity to guitar volume attenuation are top priorities, germanium is probably the way to go. The McGregor Classic Fuzz, however, offers ample reminders about the many ways silicon Fuzz Faces can be beastly, sensitive, and sound supreme.
Even though the two BC107B top hat transistors will look familiar to many who have poked around other SFF-style circuits, the Classic Fuzz is not precisely a silicon Fuzz Face clone. It’s distinguished by a low-pass filter “bass” control that true SFFs lack, but which widens its vocabulary extensively. In an A/B test with a solid, archetypal-sounding BC108 Fuzz Face clone, the Classic Fuzz sounded roughly equivalent at the 60-percent mark of the bass control’s range. But the Classic Fuzz was more dimensional, and on either side of the bass control I heard many intriguing tone variations spanning garage-punk snot and corpulent, almost triangle-Big Muff thickness.
Like most SFFs, the Classic Fuzz sounds best with a generous spoonful of amp volume. I ran it with a Fender Vibrolux just on the clean side of breakup. At amp volumes much lower than that, the fuzz voice thinned, the nuanced responsiveness to guitar volume attenuation dropped off, and the range of clean tones became much narrower. In its happy places, though, the Classic Fuzz rips—lending sparkling overdrive colors and banshee-scream aggression to Stratocasters and sounding especially sweet and terrifyingly mammoth with humbuckers

Diamond Dark Cloud
diamondpedals.com
The art of using and building delays is, at this point, a discipline populated by a thousand little cults. Vintage-minded analogists, digital micromanagers, and seekers of chaos all live under this strange umbrella. What’s refreshing about Diamond’s Dark Cloud is the way it spans so many points on the echo spectrum without 30 push-buttons and an enclosure the size of a cigar box.
It does many of the things detail-minded sound crafters demand of their delays, like tap tempo and creating precise subdivisions fast. And while it’s a digital delay, it seems very carefully designed and EQ’d to feel very analog, vintage, patinated, and moody. Indeed, in many situations it proves worthy of its name.
Crafted for Controlled Chaos
The sturdy, Canada-built Dark Cloud is a nice study in design efficiency. While there are enough tightly packed controls and switches to make some players nervous, the Dark Cloud does a lot with four knobs, a mini-toggle, and two footswitches. The toggle doubles as a mode selector when you click down and a subdivision switch when you click up. Footswitches serve the function of tapping out tempo, instantaneously or momentarily doubling delay rate, or setting up the harmonic delay mode for octaves or fifths. And though the four knobs for delay time, mix, feedback, and modulation rate are ordinarily enough, each functions quite differently depending on the mode, making the Dark Cloud deceptively simple.
Softly Spoken Expansiveness
Tape mode is, needless to say, well suited for the Dark Cloud’s darkish tone profile. Repeats drift and dissolve into mist as the echo signal degrades, and in traditional sorts of tape delay settings (short-to-medium-length delays, a 50/50 mix, and anywhere from two to five repeats), the Dark Cloud maintains a responsiveness and a not-too-overbearing presence that are simultaneously spacey and subdued. But the tape setting is also fantastic at more extreme settings. Fast repeats mated to speedy modulations and maxed-out feedback levels yield results that sound like Joe Meek wrestling a Space Echo, and you can create many accelerating/decelerating oscillation effects that suggest the old Roland tape delay standard-bearer if you engage actively and in real time with the controls.
“Fast repeats mated to speedy modulations and maxed-out feedback levels yield results that sound like Joe Meek wrestling a Space Echo.”
Harmonic and octave-up effects paired with reverbs and delay have a way of generating polarizing effects. I am generally on the side of those who find that a little goes a long way, and that too much is a saccharine tone nightmare that evokes being eaten alive by Smurfs. If you want to be devoured by wee cannibals, that’s your business, and the Dark Cloud will go there, particularly if you run wild with the feedback control. But the pedal also makes space for mellower applications. I had great luck with slapback delay times, fast decay, moderate mix levels and modulation rates in the ballpark of a Leslie’s whirl. In this setting, the harmonic delay took on the feel of an old Vox or Farfisa organ tracking my chord melody. If you stray from the Duane Eddy zone on the fretboard, single-note melodies tend to bring out the harmonic delay’s more cloying side. However, if you dig the shimmering qualities associated with these effects, you’ll find the Dark Cloud is a rich source for them, especially if you tinker with the harmonizing fifth setting on the pedal.
The Dark Cloud’s reverse delay mode is the one where the dark and cloudy facets of its personality become really intriguing. Like the tape mode, it’s a great match for drive effects from mellow boosts to gnarly fuzz—whether you situate it upstream or downstream from the pedal. But using the effect in clean settings reveals a lot about how the pedal’s EQ emphasis and duskier repeats make reverse echoes more seamless, organic, and something closer to the effect of reverse tape, especially when you keep the modulation and feedback to a minimum. In this way, the Dark Cloud’s reverse delay betters that of many of its peers and makes echoes sound less like they were grafted on as an afterthought. The reverse-echo textures can also range to more mangled extremes. If you’re a fan of Daniel Lanois’ warped-echo-and-melting-tweed-Deluxe sounds, adding fuzzy gain and attenuating your guitar tone generates a spiraling, hazy distorted signal that sounds a little like a reel of 2" coated in dust and molasses. (There’s an audio sample of that kind of thing attached to the online version of this review.)
The Verdict
If I’d had my way, I would have nixed the Dark Cloud’s harmonic delay mode, stuck with the very nice tape and reverse modes, and charged a little less. Still, a lot of players will love the many strange high-pitched and pixilated sounds available via the harmonic mode. And together, the three modes add up to a uniquely varied echo unit that can see a player through many moods—from deeply psychedelic to hyperactively effervescent.

Gamechanger Audio Auto Delay
gamechangeraudio.com
From the outset, it must be said there are easier ways to get a delay sound than using Gamechanger’s Auto Delay. But if simple echoes were the sole objective of this pedal, I doubtGamechanger would have bothered. As you may have gleaned from a listen to the company’sBigsby Pedal,PLASMA Pedal fuzz, orLIGHT Pedal reverb, the Riga, Latvia-based company rarely takes a conventional approach to anything they design or release. But what is “conventional” from a guitarist’s point of view, may be something quite different for musicians determined to bend notions of what sound and music are, how it’s made, and by what means.
By Gamechanger standards, the digital Auto Delay (along with its stablemates the Auto Reverb and Auto Chorus) is almost straightforward in concept. It utilizes existing concepts of dynamic delay, control voltage, and modular synthesis as essential parts of its functional underpinnings—which are not exactly unusual in stompbox design. Yet the way the Auto Delay’s functions interact make it feel and sound unique. And while not every player will want to take the time to explore the sometimes complex interplay between its functions, at its best, the Auto Delay prompts unorthodox thinking about the ways touch dynamics or pitch relate to the delay colors you can create, prompting unexpected compositional vectors and a kind of extra-dimensional relationship to the fretboard.
Beat of a Different Drum
Gamechanger’s path to building such unusual sound manipulation machines might seem a curious one when you consider that founder Ilja Krumins and his fellow founders Mārtiņš Meļķis and Kristaps Kalva are rockabilly heads with tastes that include the soulful earthiness of J.J. Cale. But the more accessible side of the Gamechanger design team’s musical interests likely informs the most approachable aspects of the Auto Delay. You can use it like you would any ordinary stompbox echo and take advantage of its three very distinct voices (tape, analog, and digital), copious 2-second delay time, and rangy tone control in order to fashion many compelling delay sounds. This is, needless to say, a vast underutilization of the Auto Delay’s powers.
Routing, Rearranging, and Raging Like a Lunatic
Though you can get lost in the Auto Delay (in good ways and bad), it isn’t necessarily the headache that its patch bay, LEDs, and many switches and knobs suggest. The idea behind the patch bay is simple: Routing a cable from one of the two dynamics or pitch automation input sockets to the level, tone, repeat, or time input sockets means that a change in, say, your picking intensity (dynamics) or where you play on the fretboard (pitch) increases or reduces the value for the parameter you linked to the dynamics or pitch socket. Even if you’ve not been indoctrinated in these methods via modular synthesis, it’s not as complicated as it sounds, and trial-and-error experimentation yields intuitive understanding of these interactions quickly.
The tape, analog, or digital voice can drastically reshape the tone and response of interactions. But so will the fast, rise, and gate dynamics modes, which determine the nature of the dynamic response. Setting thresholds for the dynamic and pitch response is easy. You simply hold down the “auto” footswitch or the bypass footswitch and twist the respective knobs until you reach the desired threshold, which is indicated by the adjacent LED. Like the other functions, getting a feel for how these thresholds work within your playing style takes time. As you might guess, we’ve really only discussed the most fundamental functions here. But in addition to these, you can use alt mode to assign different values to the secondary knobs and toggle between primary and secondary knobs using the auto switch. You can also manipulate the stereo spread or control the clock via MIDI.
The Verdict
The Auto Delay is not for the faint of heart or impatient. Grasping the interrelationships between the controls takes time. In fact, understanding how those interrelationships feel and respond musically will be more challenging for some than understanding how they work conceptually— which, while not elementary, can be sussed out with a careful read of the manual. But when you do find a rhythm and flow with the Auto Delay it can be richly rewarding and even meditative.
Because it can reshape your relationship with the fretboard and your sense of touch, this is a great tool for extracting yourself from ruts, whether in technique or mood. And if you’re a musical tinkerer, the Auto Delay can provide much of the same satisfaction and sense of discovery you experience working with a synthesizer—particularly if you enjoy working in the hardware realm rather than on a computer screen. One should consider the scores here as especially subjective and on a sliding scale. The Auto Delay’s many sonic and functional idiosyncrasies will be nectar to some and poison to others. And more than most pedals, you should probably have a firsthand experience with the thing before you decide how and if it fits your musical objectives. For many restless players, though, the Auto Delay will be a deep well of musical provocation and ideas.
