A Spirited Soundscape Generator from Covet’s Yvette Young

Crafted in collaboration with star math-rocker and stompbox obsessive Yvette Young, the Walrus Audio Qi Etherealizer is a multi-effects masterwork that unlocks expansive and enveloping atmospheric textures. This pedal’s tripartite configuration of effects includes two choruses, a tap tempo-enabled digital delay, and two Grain voices, with the ability to run these captivating sounds in series (Chorus into Delay into Grain) or parallel (all three effects summed together). Each of the Qi Etherealizer’s portions sports a plethora of parameters to shift and shape your signal. You also get a global control section that supplies Mix/Dry adjustment, a powerful resonant lowpass filter Tone control, and a lush reverb that transforms from a resonant room to a cavernous echo with the twist of the Space knob. To top it all off, Walrus Audio enabled this powerhouse box of ambient allure with true stereo ins and outs, MIDI In/Thru 1/8-inch ports, and a trio of onboard preset slots. All in all, the Qi Etherealizer is the ideal example of a stompbox that rewards experimentation and, in Yvette’s own words, is aimed to inspire guitarists “to sound a little less guitar-y and more . . . magical!”

Comprehensive chorus section

First up on the list, this pedal’s Chorus section comprises two distinct sounds to swap between: Tri and Stereo.

  • Tri Chorus: By combining a trio of chorus voices into a lush and enveloping whole, Tri Chorus supplies you with a rich, complex, and multifaceted wash of modulation.
  • Stereo Chorus: As you might have guessed from the name, Stereo Chorus grants you a classic chorus tone, only with the modulation of the effect offset 180 degrees to the right channel, resulting in an expansive stereo effect.

Gorgeous granular effects

The Qi Etherealizer’s Grain section selects and triggers small samples (grains) of your signal, modifying them in various ways to result in an effect that oscillates between stuttering glitch effects and exquisite, ever-moving textures. Two distinct voices of Grain are at your command, while the Playback knob provides five positions to determine how your grains are warped: normal speed, double speed with an upper-octave effect, half-speed with a lower-octave effect, reverse playback, and a setting that randomizes between all four modes for all-out chaos.

  • Grain Cloud: A favorite feature of Sweetwater’s brave ambient explorers, this mode randomly selects portions of your playing to send through the Grain section, releasing them in a sporadic fashion for always-surprising sonic anomalies. In this mode, the Qi Etherealizer’s X knob dictates the length of your individual grains, taking you from rapid clusters to more irregular activations.
  • Phrase Sample: In comparison, this mode triggers grains rhythmically, tracking initial peaks in your signal and playing back your grains starting from these peaks. In this mode, the X knob controls the tempo of the samples. Moreover, turning this knob to its lowest position syncs the Phrase Sample engine to your Delay time.

Clean and pristine digital reverb

Considering how colorful the Qi Etherealizer’s Chorus and Grain sections are, it’s fitting that the digital delay section is reasonably straightforward — think of it as a blank sonic canvas for this pedal’s more tumultuous textures! Aside from its frenzied self-oscillation function — accessible by momentarily holding down the tap tempo footswitch — this section represents a rock-solid digital delay, offering up to two seconds of repeat time and clean, crisp repeats.

Walrus Audio Qi Etherealizer Features:

  • Crafted in collaboration with genre-defining math-rocker Yvette Young — leader of her band Covet, a boundary-pushing guitarist, and a true stompbox obsessive

  • X knob unlocks voice-specific parameters when Grain mode is selected
  • Freeze footswitch unlocks momentary mayhem when you’re in Grain mode

Reviews

Very weird and cool.
This thing makes all kinds of crazy sounds. I've never tried anything like it. Lots of fun. Probably has something for almost everyone, except hard-core blues guys, but even then, who knows? Hopefully Dave "Edge" Evans doesn't get one and ruin it for everyone else.

Yeah. It's super expensive, so, there's that...
Music background: Puke rock and goofy crap
Best In Class Ambient Pedal
I own many ambient pedals from Walrus, Strymon etc., but let me tell you why this is my favorite. This takes my favorite aspects of the Walrus Audio Julia, Lore, Fable, and Slo and put it into one pedal. Put everything at noon and set the granular to 2x and you will lose yourself in ethereal bliss for endless creativity. Dial it in further to your taste and use tap tempo to match your BPM and it does what you want it to do. Use it to color your solos with tasteful layers that never overwhelm your lead tone or create a spacial blanket of ambient sound that could fill the deepest corners of space. The price tag is hefty, but I see this as a true quality 4 in 1 circuit that will inspire you in endless ways. I wish you all could have the experience I did using this for the first time in a live show and peoples faces being mesmerized by the effects and also wondering "How is he making that sound?". My pedalboard was highly talked about that night and I proudly told them its thanks to the Qi pedal and not backing tracks (Which a lot of people thought it was). This is your 1 stop shop pedal for ambience and modulation.
Over the moon
This has made my guitar production so much more interesting. I just play something into it and press record and let it generate ideas for me. Then I comp. Reverb sounds massive, and the parallel/series option is game changing.
Tip: for a wider stereo sound add chorus to any of the granular pad features


Also chorus maxed out on parallel sound sparkliest!
Lots of Fun
Pros - wow, can this pedal create the swirling ambient sounds. So much fun playing with it.

Cons - it doesn't seem to like playing nice with other pedals. Chaining it with other pedals, either in front or behind, it gets real noisy. (It's entirely possible that I'm doing it incorrectly)
