The Walrus Audio Polychrome is a fully analog, true bypass flanger pedal designed for rich modulation and versatile tone shaping. Borrowing its intuitive control layout from the Julia and Lillian, the Polychrome delivers a wide spectrum of flanging textures—from subtle shimmer to dynamic, pitch-bending vibrato.

At the heart of its sound design is the D-F-V (Dry, Flange, Vibrato) blend knob, allowing you to sweep from unaffected dry signal to traditional flanging or full-on vibrato tones. A Shape switch offers three distinct LFO waveforms—sine, triangle, and random—while the Voice switch toggles between two tonal modes: a classic full-range flange or a more complex, notched version with reduced low-end response.

With top-mounted jacks, soft-switch relay bypass, and rugged construction, the Polychrome is as pedalboard-friendly as it is sonically flexible. Whether you're after traditional analog flange or more experimental modulation, this pedal offers a colorful palette of sounds for creative players.
