Walrus Audio Qi Etherealizer Multi-Effects Pedal – Used
Description
Quick Product Summary
The Walrus Audio Qi Etherealizer is a creative stereo multi-effects pedal developed in collaboration with guitarist Yvette Young, combining chorus, delay, granular processing and reverb within a single highly interactive unit.
This used example is in Good condition, showing visible signs of previous use consistent with a pre-owned effects pedal. With series or parallel effect routing, presets, MIDI control and hands-on Freeze and oscillation functions, the Qi is designed for everything from subtle modulation and delay to expansive ambient textures and experimental soundscapes.
What Makes the Walrus Audio Qi Etherealizer Special?
Rather than treating its effects as completely separate processors, the Qi allows Chorus, Delay and Grain sections to interact in either series or parallel. Series mode runs Chorus into Delay and then Grain, while Parallel mode processes each independently before combining them. A dedicated Space control adds reverb, while the Tone control uses a resonant low-pass filter to shape the overall wet signal.
The granular section offers both Grain Cloud and Phrase Sample modes, with five playback options including normal, double-speed/octave-up, half-speed/octave-down, reverse and randomised playback. Combined with tap tempo, momentary Freeze, delay oscillation and onboard presets, the Qi can move from conventional modulation to highly unusual evolving textures.
Who Is It For?
The Qi Etherealizer is ideal for guitarists and other musicians interested in ambient, math rock, post-rock, experimental, shoegaze and cinematic sounds.
It is particularly well suited to creative players who enjoy building layered textures from several interacting effects rather than using separate chorus, delay and reverb pedals in a conventional signal chain.

FAQs
What type of pedal is the Walrus Audio Qi Etherealizer?
The Qi is a stereo multi-effects pedal combining chorus, digital delay, granular sampling and reverb within a single unit.
Who designed the Qi Etherealizer?
It was developed by Walrus Audio in collaboration with Yvette Young, guitarist and founding member of Covet.
What is the Grain effect?
The Grain section captures very short pieces of your playing and replays them in different ways to create glitchy, rhythmic and atmospheric textures.
What is the difference between Grain Cloud and Phrase Sample?
Grain Cloud randomly triggers small samples from your playing for less predictable textures, while Phrase Sample detects musical transients and produces more rhythmic sample playback.
What grain playback options are available?
The Qi provides normal speed, double-speed with an octave-up effect, half-speed with an octave-down effect, reverse playback and a random mode that combines the different behaviours.
What chorus sounds does it offer?
The pedal includes Tri Chorus for a rich multi-voice modulation sound and Stereo Chorus, which offsets the modulation between the left and right channels for increased stereo width.
How long is the delay time?
The digital delay provides repeats of up to approximately two seconds.
Does the Qi have tap tempo?
Yes. The TAP/OSC footswitch allows the delay time to be tapped in during performance.
What happens when the TAP/OSC switch is held?
Holding the switch increases the delay feedback and pushes the delay into oscillation for creative performance effects.
Can the effects be routed in different ways?
Yes. Series mode feeds Chorus into Delay and then Grain, while Parallel mode processes the three effects independently and combines their outputs.
Does it have presets?
Yes. There are three onboard presets — Red, Green and Blue — plus a Live mode for the current physical control positions.
Does it support MIDI?
Yes. The Qi provides 1/8" TRS MIDI In and MIDI Thru, with extensive parameters accessible via MIDI control.
Does it work in stereo?
Yes. It has dedicated left and right inputs and outputs for full stereo operation.
What does the Space control do?
Space adds reverb to the processed signal, moving from smaller ambience at lower settings through to large, diffused ambient reverb at higher settings.
What does the Tone control do?
Tone adjusts a resonant low-pass filter applied to the wet effects, allowing brighter or darker atmospheric textures to be created.
Does it have true bypass?
No. The Qi Etherealizer uses buffered bypass.
Can it run from a battery?
No. It requires an external 9V DC power supply capable of providing at least 300mA.
Is a power supply included?
No. No power supply is included with this used pedal.
What condition is this example in?
This example is graded Good, with visible cosmetic signs of previous use consistent with a pre-owned effects pedal.
