Used Walrus Audio POLYCHROME Effect Pedal

The Used Walrus Audio POLYCHROME Effect Pedal is a dynamic analog flanger offering lush, studio-quality modulation in a compact, durable enclosure. In great condition, this stompbox features selectable voice modes—traditional, random, or negative feedback—for a wide range of tonal textures. Its intuitive control layout includes rate, depth, sweep, and feedback knobs, along with a dedicated D-F-V (Dry-Filter-Vibrato) blend knob for tailored sound sculpting. The true bypass switching ensures your tone remains pure when the effect is disengaged. Powered by a standard 9V center-negative power supply (not included), the Polychrome is perfect for players looking to add shimmering flanges, sweeping sweeps, or warped, experimental tones to their rig. Ideal for guitar and synth enthusiasts alike, this pedal delivers rich analog character and creative potential in a reliable used unit.
