Walrus Audio Julia V2 (Black)

The Essentials to Know About the Walrus Audio Julia Analog Chorus/Vibrato Pedal

• 100% Analog Chorus and Vibrato, from smooth and subtle chorus to fully embraced "seasick" vibrato


• D-C-V Blend Knob for seamless navigation between dry signal, chorus, and vibrato (much more musical than a simple switch)


• Lag Control to adjust the sense of "width" and delay, from tight modulation to undulating detune


• Two LFO Waveforms (sine and triangle) to switch from a smooth movement to a more defined modulation

Julia: A Walrus Audio Icon, Between Legend and Reference Pedal

The Julia is one of the pedals that built Walrus Audio's reputation: a modulation with a strong character, designed to inspire as much as to serve. While many choruses simply thicken the sound, the Julia offers a true gray area between chorus and vibrato, with textures ranging from "vintage chic" to deliberate instability.

And then there's the story: a mysterious moan from the depths, an elusive aquatic deity... Walrus transformed this mythology into a sonic identity. In practice, the Julia mainly captures what guitarists seek in a great analog chorus: substance, dynamics, and a modulation that lives with your playing rather than floating above it.

Which Guitarists (and Bassists) Is the Julia Made For?

The Julia is aimed at musicians who want an expressive modulation pedal, capable of being subtle in rhythm parts and spectacular in leads. On clean tones, it adds width and a "3D" sensation ideal for pop, indie, funk, neo-soul, or ambient music. With overdrive or fuzz, it becomes grittier and more fluid, perfect for alternative rock, psychedelia, and shoegaze textures.

Thanks to the range of the D-C-V Blend, it also works very well on bass: you can add just a hint of movement without losing attack, or conversely switch to a full vibrato for more liquid lines. In the studio, it excels at doubling takes without freezing them. Live, its controls remain clear and effective, even when you need to adjust quickly on the pedalboard.

Controls and Options: Modulation Tuned to the Millimeter

The Julia retains the basics (Rate and Depth) but goes much further in how to "shape" the modulation. Rate sets the oscillation speed, while Depth defines its intensity. The heart of Julia's personality is the Lag: it adjusts the operating point around which the modulation unfolds, radically changing the feel from clean, tight chorus to unstable, almost sickly detune, typical of vibrato.

The D-C-V Blend knob is the other key element: at minimum, you stay on your dry sound. Around noon, you get the "traditional" chorus (balanced dry and wet mix). At maximum, you switch to 100% wet vibrato. Between these positions lies a very personal palette: micro-movements to thicken, watery chorus, then chorus-vibrato hybrids impossible to achieve with more conventional pedals.

Finally, the Wave switch (sine/triangle) allows you to tailor the texture: the triangle shape brings a more defined movement, often very convincing in chorus mode, while the sine provides a rounder, more natural sway, particularly pleasant in vibrato.

The Sound

The Julia has a warm and organic signature typical of analog modulations, with a very "instrument-like" response. It reacts well to pick dynamics and volume changes: the harder you play, the more present the movement feels; the lighter you play, the more airy the modulation becomes.

In gentle chorus, it adds breadth without turning your sound into an artificial wash. Pushing Depth and Lag shifts into unstable vibrations, expressive detune, perfect for creating a worn tape feel or lo-fi synthesis... all while remaining musical. Several artists have adopted it on stage and in the studio, including Theo Katzman, Buck Meek, and John Flansburgh, proving that the Julia can both disappear into the mix and become the center of a sound.
