Walrus Audio Polychrome
The Polychrome lets you blend in the dry signal with the D-F-V knob – that stands for Dry, Flange and Vibrato, like on WA’s Julia and Lillian pedals. This allows you to go from full-dry and traditional flange all the way through to a full-pitch-vibrato setting. The other controls are Rate, Depth, Sweep and Feedback, plus a Voice switch that allows you to choose between traditional or a complex & notched voicing. Three LFO shapes are on offer, too, with sine, triangle or random selected using the Shape switch.
Lots of control
For such a compact pedal, this analogue flanger has a lot of variety going on. The Rate knob sets LFO from a super-slow 0.1 Hz to 8Hz, whilst the LED previews the LFO speed so you know where you are. Using the Depth knob, you can adjust the width of the filter sweep, whilst the Sweep knob adjusts how deep the flange is from a tight setting through to more traditional flanger tones. Then finally the Feedback control goes from subtle through to more dramatic over-the-top flanging.
The pedal is true-bypass and uses a smart momentary bypass switch.. It’s got top-mounted jacks, so it’s pedalboard friendly. It runs off a 9 V centre-negative power supply and requires 100mA, so thankfully doesn’t have huge power draw.
If you enjoy a good flanger pedal and need something compact then I feel the new Walrus Audio Polychrome should be on your “Pedals to Check Out in 2021” list.
