Walrus Audio Fundamental Chorus

A Chorus Designed for the Essentials, in the Spirit of Classic Modulations

The chorus is one of the most iconic modulation effects: it doubles the signal, slightly shifts it, and moves it to create that sensation of width, depth, and "movement" that has marked both crystalline clean sounds and thicker textures. With this Fundamental pedal, the idea is to rediscover the immediate pleasure of chorus by offering a coherent palette in three intensities, while keeping an intentionally simple and very readable interface.

For Which Guitarists (and Situations)?

This chorus pedal is aimed both at beginner musicians who want a first clear and effective modulation effect, and at experienced guitarists seeking a chorus that is quick to set and reliable live. It works particularly well on clean sounds (arpeggios, open chords, funk, pop) but also after a light overdrive to thicken a lead or add depth to a riff. In the studio, it helps widen a take without drowning it, and on stage it brings movement that helps the guitar breathe in the mix.

Features and Controls: Simple, but Not Simplistic

The ergonomics focus on three essential settings. Rate adjusts the modulation speed (from slow and dreamy to more nervous), Depth controls the depth of the wave (subtle or very pronounced), and Mix balances the blend between dry and modulated signals to go from a discreet thickening to a very present chorus. A mode selector allows choosing between Light, Medium, and Heavy : practical for immediately adapting to the song, gain level, or available space in the mix. The On/Off footswitch ensures classic and direct use, perfect for a pedalboard focused on efficiency.

The Sound

The sonic character is built around a musical chorus, capable of being very subtle to widen a clean sound without an "obvious" effect, or on the contrary well textured for deeper atmospheres. In Light mode, you get a thickening that respects the attack and keeps the guitar clear, ideal for clean rhythms and arpeggios. Medium mode brings a more audible movement, perfect for pop, indie, rock, and lead parts that need to stand out without adding gain. Heavy mode pushes the effect towards wider modulations, useful for pads, dreamy intros, and more marked colors, while maintaining fine control thanks to the Mix.
