Walrus Fundamental Ambient
walrusaudio.com
With variable voices, accessible prices ranging from 99 to 129 bucks, and slide controls that evoke old synths and vintage Jen pedals, Walrus Audio’s Fundamental series effects are functional, stylish, and dish a lot of awesome sounds at a nice price. The newest addition to the Fundamental series, the Ambient, will be good news for budget-constrained atmospheric musicians that otherwise settle for less-durable pedals at the market’s most inexpensive extremes. Some of those pedals are pretty cool, but the Walrus’ construction quality, sense of substance, and function—which is flat-out fun—make it a substantial alternative to those entry-level artifacts for a minor additional investment. It puts a super-wide range of sounds at your disposal, too.
Though few may use Ambient in subtle applications, it is capable of nice sounds on that spectrum. By using the lowest mix, tone, and decay settings, you can create an appealing facsimile of studio plate reverb that isn’t slathered in cloying top-end harmonics—particularly in the deep mode (which adds low octave) and the sustain-rich lush setting. At advanced mix and decay settings, the Ambient can sound colossal, alien, and unreal in ways any serious sound designer would be happy to explore. Haze mode, which uses sample rate reduction to create grainier, fractured, lo-fi pictures, is its own awesomely weird animal. You can fashion outsized dream-pop textures, or, at the most extreme level and mix settings, use the tone slider in crossfade fashion to conjure scuzzy VHS horror tones that, frankly, freaked me out as I was playing them.
A broad range of voices and a clever morph control unlock uncommon ambient reverb sounds that break the same-old-cathedral-verb mold.
Many unusual tonalities that defy affordable ambient reverb convention. High-quality controls. Morph control covers a lot of tones shifting without an expression pedal.
Setting up morph control can feel less than intuitive.

Pigtronix Cosmosis
pigtronix.com
Pigtronix boss Dave Koltai is an energetic guy—particularly when you get him chatting about music. He loves the musical potential of the guitar. And while he seems to have an affection for every kind of guitar expression, from the rootsiest to the most experimental, his heart often seems to be very invested in the latter camp. Pigtronix pedals have always hinted at that affection for out-there modes of guitar thought, and the new Cosmosis stereo reverb definitely exists, in part, to serve those urges. Billed as an ambient reverb, the Cosmosis spans big-picture reverb profiles and more modest ones. And while it doesn’t necessarily achieve anything revolutionary, it features many unique sounds and a cool, practical morph control, which enables users to shift between very divergent settings using a footswitch instead of a space-hogging expression pedal. Together with the many spacious voices on tap, it helps make Cosmosis a varied and versatile time-warping device.
More Cosmic Pig, Less Space Hog
On the surface, Cosmosis’ morph control might not seem like a big deal. But as I am often tasked with getting the most possible sounds from a pedalboard that shares a suitcase with two weeks’ worth of clean clothes, I can attest to the impracticality of expression pedals and the value of effects that do more without them. With its longitudinally oriented, rectangular layout, Cosmosis doesn’t exactly have the smallest footprint. But while you could argue that a similar set of functions would have fit in a vertically oriented box, users would have paid a penalty in functionality and practicality onstage. Cosmosis’ control layout is smartly spaced, logically laid out, and pretty easy to suss before you ever touch the manual. Tone, blend, and size controls are exactly what they seem, and they’re sturdy, smooth-turning things that are satisfying to the touch. The three small push buttons, which, perhaps, look a bit too much like the black screws holding the enclosure together at the pedal’s crown, enable switching between the pedal’s three primary voicings, four presets, and the parameters governed by the morph control.
Sorting out the functionality of the morph function takes a few minutes with the manual. Getting a feel for the switching sequences required to select and assign values can feel awkward, if only because the possible combinations are so many. While many pedals with the ability to move between settings via expression pedal can only assign that movement to a single effect, the Cosmosis' morph function allows any combination of parameters to be manipulated simultaneously. And the compound tone shifts you hear between the two extremes in many Cosmosis morph cycles can be exceptionally rich and nebulous.
Returning the Mystery to Space
The Cosmosis’ morph feature is made cooler for the varied voices the pedal puts at one’s disposal. With a voice called “temple,” you’d expect the kind of churchy, choir-like, octave-up tones associated with ambient reverb. At their best, these octave-up sounds can evoke organ tones or add lushness to overdubbed layers. At their worst, they sound like sickeningly sweet, cheap cable-sci-fi soundtracks. And the Cosmosis trades the octave-up ambient reverb technique for a smoother-sounding processing that uses just harmonics to create the reverb image. And an effective, wide-ranging tone control means you can bend that high-frequency-harmonics content to much weirder ends. At its highest extremes in the temple and even more spacious cosmos settings, the tone control adds almost granular washes that sound like the electromechanical clangs from a spring reverb taken to unnatural extremes. At some lower tone settings, the Cosmosis tucks high octave content into much more subliminal spaces, which is especially cool for adding faint illumination around the edges of foggy, extra-wet, super-spacious temple and cosmos settings.
The Cosmosis’ most demure settings are fun to work with. too. There are many convincing spring-like settings that run from subdued to splashy and metallic ’60s tones. And room-style settings can give any instrument a touch of intimate Fleetwood Mac Rumors glow.The Verdict
The Cosmosis is, delightfully, more than the average generic ambient reverb. While it can generate the high-harmonic-bedazzled textures many look for in an effect of this type, its rangy and interactive tone, space, and blend controls generate octave-up colors that are uncommon and mysterious. The sounds you can create between the modest theater settings and the grandest cosmos settings span mellow room- and amp-reverb sounds and tones that evoke spaces measured in light years. The useful morph function, meanwhile, enables the player to shift between such extremes with dramatic effect. And while some players will lament that there are only four presets, that number can accommodate hugely variable tones if you’re clever and creative. At nearly $220, its price falls in line with comparable ambient reverbs. But its unique tonalities and features will make it a superior option for many players seeking less-common routes to space-time contorting bliss.

Electro-Harmonix Pico Attack Decay
ehx.com
Mini pedals are immensely practical. I fantasize about traveling with a little board populated exclusively by them. And were it not for my attachment to a few old favorites, I might have already pivoted to an exclusively mini-pedal rig for any trip involving checked baggage.
Electro-Harmonix is a relative newcomer to the mini-pedal sphere. In fact, most of their efforts at miniaturization involved taking pedals like the Big Muff and Electric Mistress that were quite large and reducing them to sizes more in line with other company’s standard-sized stomps. But if they were a little late to the game, EHX, as they will, entered the marketplace with a sense of style and adventure. Each of EHX’s nine new Pico pedals, as EHX calls them, are part of the digital NYC DSP series. Curiously, confinement to the digital realm means this set of Pico releases is without legendary EHX pedals that would be logical candidates for miniaturization—most notably the Big Muff. But what the new Pico pedals lack in predictability, they make up for in color: Some of EHX’s most interesting pedal ideas are part of this series.
In imagining possible combinations of these nine pedals, it occurred to me that you could fashion a lot of very unique tone palettes from just a few of them. Though each of the pedals reviewed here—the Pico Attack Decay, Pico Oceans 3-Verb, Pico Canyon Echo, and Pico Deep Freeze—are evaluated on their own merits, they were selected with the notion of creating a little psychedelic sound laboratory. And while you can wring conventional sounds from these four pedals, their capacity for weaving weird and complex patterns of sound speaks to the exciting potential of these little stomps and EHX’s enduring sense of irreverence and invention.
Pico Attack Decay
The original EHX Attack Decay, an analog volume envelope that first appeared around 1980, was called a “tape reverse simulator” for its ability to generate reverse-tape-like volume swells. It’s an odd bird—even by EHX’s lofty standards. Next to the analog original, which came in a Deluxe Memory Man-sized enclosure, the Pico version is pico indeed. But this version is derived from the digital reimagination of the effect that appeared in 2019. That permutation includes a built-in fuzz, expression control, presets, an effects loop, and preset capability, but I’d guess that more than a few players will be more tempted by this smaller, streamlined version.
It's easy to create the volume swell effects that give the Pico Attack Decay its tape reverse simulator handle. You put the pedal in mono mode (activated by the small poly button), set the attack knob around the 10 o’clock position, and park the decay to the right of noon. The reverse tape effect can be pretty uncanny, and it’s fun to play leads and melodies using pre-bends, odd intervals, and off-beat timing to achieve more authentically disorienting reverse effects. These settings also make the pedal a nice stand-in for a volume pedal for simple melody lines. Certain fast attack times mated to shorter decay times produce clipped, no-sustained tones or stuttering, fractured tremolo textures. The former sounds especially amazing paired with fast echoes and long repeat times from the Canyon delay—creating spacey Joe Meek-style percolations. Used in mono mode exclusively, the Attack Decay can seem limited. Using poly mode doesn’t add oodles of additional textures, but it does often add a vowelly, mutant flange/filter effect that’s good for alien envelope-filter tones, which, again, sound pretty incredible with a heap of echo.
For the right player, the Pico Attack Decay can be an effective way to reshape instrument timbre and create interesting, off-kilter versions of volume-swell, envelope, and even bizarre staccato modulation effects. At just 20 bucks less than the larger, full-featured Attack Decay, the small size may be the main appeal here. But that mini footprint can make the difference between a niche effect making the cut when space is tight.
The Pico Canyon Echo is as engaging as any delay I can think of in a package this size. It’s flexible and full of surprises, thanks in large part to the cool filter control, a super-wide 8-millisecond-to-3-second delay range, and an infinite repeats function that effectively functions as a looper.
Sans filtering, the Pico Canyon’s basic delay voice is fairly neutral, which is no bad thing, and it’s certainly not chilly the way some digital delays can be. Introducing the filter, however, steers the Pico Canyon along unique tone vectors, particularly when you use the super-short, ADT-style delays. The filter moves between neutral no-filter sounds at noon and low-pass and high-pass settings on either side of the dial. Depending on where you set the filter and feedback control, these short delays can produce ring-modulation-like tones, lo-fi AM radio colors, and resonances and feedback effects that change dramatically depending on your pickups, amplifier, and playing dynamics. It also yields unexpected sounds that you don’t necessarily associate with delay. The filter control isn’t exclusively for oddball sounds, though. The low-pass filter adds darkness to repeats that hints at BBD delay sounds and is particularly effective for adding fog to long feedback settings. The high-pass filter, meanwhile, can lend digital crispness or ringing and howling Space Echo-style resonances with long feedback times.
Though weird sounds abound in the Canyon, it is a delay of great utility too. The tap-division button enables fast switching between eighth-note, dotted eighth-note, and quarter-note divisions, and it features a tap tempo function. With an appealing $149 price tag, I’d be tempted by the Pico canyon if it was twice the size. The combination of small size, straightforward functionality, interactivity, and flat-out fun make it an extra attractive delay option that will tempt players across many styles.
Like the Pico Canyon, the Oceans 3-Verb inhabits a crowded market space that ranges from ultra-low-priced imports to fancier fare. But while the Pico Canyon distinguishes itself from the competition with a wide range of straight-ahead to weird sounds, the Oceans 3-Verb mostly focuses on fundamentals. Here, that means digital emulations of spring, plate, and hall reverbs. The 3-Verb’s one great wild-card feature is its infinite reverb, which works in the hall and plate settings. It’s an awesome addition that ups the fun quotient exponentially and makes the 3-Verb an appealing option for noise, drone, ambient, and other experimental artists.
The 3-Verb’s voices each capture the spirit and quirks of their inspirations—often with great fidelity. The most subdued voices all add classy ambience that pairs nicely with drive pedals, adding air without turning gain-activated overtones to a filthy wash. Differences between the hall and plate reverbs are most discernible at these less-intense levels. Hall reverbs are tight and reactive with the tone, time, and pre-delay levels at modest levels. Add a little treble and you’ll hear a nice approximation of tile reflections. The plate reverb sounds most distinctively authentic with a little extra treble, pre-delay, and decay time, lending the slightly metallic and ghostly overtones that make real plate reverb so delicious. Both hall and plate reverbs can be taken to stranger lands, particularly when you add a generous helping of pre-delay, which can evoke Kevin Shields’ reverse-reverb tricks or add endless miles of ambience. At these more extreme settings, the hall reverb tends to emphasize high-octave content, while the plate is more diffuse and spectral. In both settings you can use the infinite reverb effect, generating huge washes that are beautiful when mixed with droning feedback.
As solid as the plate and hall reverbs are here, the spring reverb is the hit of the bunch. It doesn’t have quite as much body as a real Fender Reverb unit or the splashy reverb in the mid-’60s Fender Vibrolux I used for comparison. It’s also basically brighter than those two reverbs. But it is really no less awesome or fun for those differences. At advanced tone settings and in the large tank mode, it practically becomes a caricature of spring reverb. This is not a diss. I’ve gone looking for this tone many times in order to achieve extra-big-picture surf or Fillmore psychedelia sounds and come up short. It’s the kind of spring reverb that can absolutely slice through a recorded mix—even a busy one. I’d even venture that many players would pick this over the real thing.
Not every player needs an EHX Freeze. But a lot of players don’t know what they’re missing. The Freeze inhabits an interesting place among guitar effects. It is, in effect, a little sampler that grabs your signal and freezes it for a given period—sometimes infinitely. A freeze is different than just a sustained tone. There is a lag in a freeze capture that can add many overtones. They can be pretty or ugly, depending on the moment you capture, the relationship between dry and effected signal, and how long you freeze the audio picture you capture. Put another way, the Freeze can be a drone machine, a chilly digital cimbalom, a tamboura in a box, a synth-generated sine wave, a freeze-frame ring modulator, or a distant ship’s horn sounding through the fog. Getting predictable and harmonious outcomes can take a steady hand, a bit of concentration, a smooth touch, and familiarity with how the Freeze’s interesting controls interact. But in and among these strange tone relationships await interesting sounds that can add gobs of extra vocabulary to your electric guitar expressions.
The Deep Freeze features three modes of operation: latch, moment, and auto. In latch, Deep Freeze grabs and holds your signal at the moment you press the footswitch. In moment mode, the pedal holds the freeze for as long as you hold the foostswitch. In auto mode, the Deep Freeze grabs the last note you play, enabling you to freeze each note in a sequence. Controls for dry and effect manage the critical balance between dry and effected signal. Gliss controls the speed at which an existing freeze morphs into a new one. The speed/layer knob controls the volume envelope in auto or moment mode, and in latch mode, it controls the volume of the previous freeze as you layer in new ones. That probably sounds complex, but it’s surprisingly easy to feel out the interactivity between these controls.
If there is a fundamental bit of knowledge with which you must approach the Deep Freeze, it’s that it likes to capture pure notes or chord tones without too much dissonance, which will cause fluttering freeze tones colored with cold digital artifacts. If you want a prettier, more unadulterated freeze—particularly in latch and moment modes—it’s critical that you freeze the note or chord at the most harmonious point of its bloom. If you hit the switch right as you pick a note or hit a chord, overtones from pick attack that might otherwise go unnoticed turn into dissonant rattle. Likewise, pitch changes or irregularities—from hitting your vibrato arm as you freeze a chord, for instance— will turn into the same digital clatter. In auto and moment modes, I got best results by using a soft picking touch and waiting for the sweetest moment of a note or chord bloom to hit the switch. Harmonics, too, can make beautiful drones if you capture them at their most beautifully blossoming moment.

Electro-Harmonix Spruce Goose
ehx.com
I was very late to discover the Marshall Bluesbreaker. There’s no reason, really. We just didn’t cross paths often, and unlike, say, a Boss SD-1 or something, there wasn’t one lurking around every practice joint. Last year, though, I got to hang out with Marshall’s recent re-issue and was sad to see it go. So, I was equally stoked to get my hands on EHX’s Spruce Goose, which uses the Bluesbreaker as a point of departure.
The Spruce Goose (and the circuit it’s derived from) are popularly regarded as low-gain drives. I’m never sure where the threshold between low gain and something nastier lives. But the Goose sometimes pulls to the aggro side of that line like a mad dog on a leash. It doesn’t take a lot of work to make the Spruce Goose explosively alive, and it’s quick to wake up a thin amp. Telecaster bridge pickups can sound firecracker hot and SG Burstbuckers beastly. With the latter, you can transform any decent black-panel Fender-style amp turned up to 7 or 8 into something a lot like a Marshall in the service of Angus. Those single-coil sounds are my favorite, though. Via the Goose, they come through clear, snarly, rowdy, and rude. That clarity crossed with filth extends the Goose’s utility. High-octane folk rock arpeggios, Zep’ I lead stingers, Black Flag grind, and Sonic Youth yowl all sound perfectly at home in the cradle of the Spruce Goose. Mind the boost from that lift switch, though. It’s a little like pouring nitroglycerin on a stack of twitchy dynamite. Hearing it blow is a rambunctious pleasure.

Headrush Prime
headrushfx.com
The Headrush Prime is an extremely deep all-in-one floor modeler that brings a few distinctive features to a very competitive space. With just seven knobs and a full-color touchscreen, navigating through the various menus and options is relatively easy—a big plus for those hesitant to take the digital plunge. The array of included effects, amps, and cabs is impressive and the main food groups are all represented. One of the most intriguing features is the Amp Cloner, which “clones” any amp, preamp, overdrive, distortion, or fuzz pedal. I tested it out with a homemade clone of a Zendrive and the process was very easy. The Prime captured the essence of the pedal without much digital stiffness.
This space doesn’t permit an exhaustive look at every feature on the Prime. But I was very impressed with the graphics on the touchscreen. Pedals and amps look much like their real-world counterparts and, thanks to a few routing templates, creating nearly any imaginable rig is a relatively smooth process, though the manual remains essential. High-gain sounds are among the strongest here, and models of Soldano and Mesa/Boogie amps are standouts. At $1,299, the Prime holds its own against other floor modelers in its class, and it’s a worthy option for players who want authentic tones without navigating endless screens of menus.
