Walrus Audio · pedal

The Walrus Audio Polychrome is an all-analog flanger that delivers warm, immersive modulation rather than the harsh, brutish jet-plane sounds of vintage flangers. It adds a warm neon glow that sits comfortably in a mix and shifts in trippy, fun ways, and at slower rates with high feedback it produces a gooey, underwater version of the classic whooshing jet-flange. A D-F-V knob blends from full dry through traditional flange at noon to full pitch vibrato at maximum, and interactive depth and sweep controls allow tight, focused tone shaping with some practice. The all-analog design gives a rich range of warm flange textures. It suits players wanting smooth, musical, warm analog flanging, from subtle movement to gooey underwater sweeps and pitch vibrato, across rock, ambient, and creative styles in a versatile pedal.
