When it comes to effects like phase, chorus, and vibrato, many of us tend to have a staple (and sometimes cheesy) sound in mind. But such preconceptions obscure the reality that these effects can be much more radical than their best-known applications.
If you’ve ever thought that phaser pedals are one-trick ponies, All-Pedal’s new Microdose, a digital phaser collaboration with Portland’s Spaceman Effects, will happily relieve you of that notion. The Microdose is to the MXR Phase 90 what the modern smartphone is to an old Nokia flip phone: It’s so feature-packed and overflowing with an embarrassment of tone riches that it feels barely related at all to its humble ’70s ancestor.
“It gets percussive, punchy, and juicy, turning single-note runs into intergalactic transmissions, and full chords into blasts of alien goop.”
Discoveries From the Outer Reaches of Space(man)
The Microdose is an evolution and expansion of Spaceman’s Explorer Optical Phaser. It’s maximalist in terms of both enclosure art and functionality, and can feel a bit cluttered as a result. Between eight knobs, two switches, two footswitches, and a groovy font and graphics vying for visibility there is a lot to take in. There are a lot of sounds too. The crowning achievement here is the collection of 16 wave forms—more than triple the Explorer’s five—all of which are selectable via an 8-stop rotary knob and a switch that moves between standard or alternative (and weirder) versions of each wave form. Each setting can be treated to two-, four-, or eight-stage phasing, and the level control provides a hearty boost for the effect to make sure that when its engaged, differences between settings won’t get lost.
Rate, multiplier, blend, and depth knobs all function as you’d expect them to, but the Microdose’s resonance and warp controls breathe new life into familiar sounds. Resonance controls phaser feedback, generating gentle, tried-and-true phase sweeps at low settings and more prominent, insistent phasing when cranked the other way. Coupled with the depth knob, it allows for precise tuning of intense phase sounds. The warp knob, meanwhile, does exactly what it says: At noon, the phase wave form remains unaltered, but turning it in either direction produces varied modifications to each wave form.
The Microdose’s tap tempo is a welcome addition that adds flexibility and more control over complex modulations—especially in live situations. But with such a vast expanse of sounds on tap and no preset functionality, the pedal’s usefulness on stage can feel limited. While dedicated phase jockeys will no doubt find a spot for it on their gigging boards, it sometimes feels more like a piece of studio kit.
Mind-Expanding Tones
The Microdose lives up to its name. It can give you a subtle, just-fun-enough, vintage experience if that’s what you’re after. But it can also blast way beyond that into sci-fi, psychedelic, and fearsome ghost-in-the-machine meltdowns that sound nothing like guitar.
Set for a classic, two-stage sine wave phase with all controls at noon, the Microdose is surprisingly unassuming, adding just a sliver of movement and dimension. This is where the pedal’s dense tweakability really shines. You can dial in a modest always-on sound that breathes life and unusual texture into rhythm or lead parts without overpowering your signal. Deep depth and blend will swing you well into Waylon Jennings territory, but that’s just the start.
Things get trippy in the best way possible as you add phase stages and explore the alternative wave form algorithms, which are a lot of fun on their own and even more so with a wiggle of the warp knob. With each bump up in stages, the effect gets waterier and three-dimensional, which feels like splashing around in some interstellar swamp. When you max out at eight, the effect is in the driver’s seat. It gets percussive, punchy, and juicy—turning single-note runs into intergalactic transmissions, and full chords into blasts of alien goop.
The Verdict
There’s a whole world of sounds here between the Microdose’s extremes. It can probably execute every single phase sound you’ve ever dreamed of—plus some wackier than what your puny human brain could come up with without lysergic inspiration. If you’re up for a phase experience, Microdose is a trip you’ll want to take. PG
So, the Eventide Riptide is, in some ways, the pedal of my downsizing dreams. It consolidates excellent digital approximations of the optical-circuit-based Shin-Ei Uni-Vibe and variations on that theme, with two digital overdrives. The two effects can be used independently or together, and you can flip the routing of both. The Riptide also allows the player to dig deep into the possibilities of these sounds, offering stereo output, five onboard presets, and expression pedal functionality that enables you to change any parameter, in any direction, with a single expression pedal sweep. There are certainly cool possibilities here that a dedicated overdrive and Uni-Vibe or phaser effect cannot easily cover.
Born of the Mothership
Like the TriceraChorus stomp that Eventide released in 2021, the Riptide has origins in algorithms from the capable and expansive H90—in this case the Weedwacker Tube Screamer-style overdrive and the Even-Vibe Uni-Vibe model, which, together, make up the H90’s Hendrix-inspired Indigo Fog preset. The Riptide features two variations on those algorithms in the form of a less midrange-y red overdrive (selected via the small button above the drive footswitch) and a red Uni-Vibe setting, which is a more phase-forward take on the green Uni-Vibe sound.
On the Uni-Vibe side of the effect, the controls essentially correspond to that of a real Uni-Vibe, with the partial exception of the vibe knob, which at some counterclockwise settings effectively doubles as an effects-level control. At its furthest clockwise position, the vibe knob removes the unaffected signal, taking the place of the vibrato setting on a Uni-Vibe rocker switch and producing pure pitch-vibrato. At noon, the control approximates the sounds of a Uni-Vibe in its more famous chorus mode (which actually functions more like a phaser, but that is a story for another time). This configuration of the vibe control means you can create blends of the vibrato and chorus effect or, on the counterclockwise side of noon, use high intensity modulations at low mix levels. This extends the utility and musical flexibility of the vibe effect significantly. The three knobs assigned to the drive side of the pedal—drive, tone, and level—are the same as the Tube Screamer and other drive pedals.
Watch for Wobbly Drivers
No Uni-Vibe worth its salt is subtle, but the Riptide is extroverted in its own way. It’s unmistakably a Uni-Vibe sound, and a nice one at that, with plenty of chewy, vocal elasticity in the modulations. But compared to real Uni-Vibes I’ve met (memories of which are less than fresh) and the modern optical vibe effect I used for reference, the Even-Vibe section has a slight high-mid and treble emphasis that, to my ear, makes some intense modulations a little less rubbery and vowel-y. There are advantages to this kind of tone profile. Humbuckers sound a lot less muddy with heavy modulations, for one thing, and if you use Fender-style single-coils it’s unlikely you’ll go missing in a mix.
“No Uni-Vibe worth its salt is subtle, but the Riptide is extroverted in its own way.”
The toppier profile also has advantages in many of the blended chorus and vibrato settings, and when the modulations are backgrounded in the mix. In the former, the extra high-end seems to accent some pitch wobble effects, lending complexity and cool whistling overtones to combined chorus/vibrato voices. In the latter application, it contributes a little extra cut to low effect mixes that lends a ghostly presence. The phasier “red” voice, by the way, does strike a cool balance between Uni-Vibe and Phase 90-style tones. But it also offers sounds that exist outside the Uni-Vibe canon that will give more experimentally minded players lots to work with.
The Verdict
There are few modulation textures as liquid or capable of shifting the mood of a song as a Uni-Vibe. The Riptide has the same power to compel and push a song or a player’s approach in soulful, manic, and explosive ways. It has its own tone signature, and for many players that high-mid-forward emphasis will be preferable—particularly, I would guess, for Hendrix and Gilmour fans trying to coax Fuzz Face and Marshall qualities from, say, a Les Paul and a Fender Deluxe. You could argue that $299 is steep for such a specialized effect. But you’ll pay at least that much for an overdrive and a decent Uni-Vibe clone with many fewer routing and customization capabilities. If you’ve never messed with a Uni-Vibe clone before, a world of weird and wobbly awaits. But purists, too, will find plenty of thrills in this smart, compact combination of effects.
