Walrus Audio Polychrome Analog Flanger
Polychrome · Walrus Audio
52 for sale on Reverb1 finish at Thomann
- Weight0.35 kg
If you want a flanger that can go from a subtle swirl to a deep, dramatic sweep, this pedal is worth a look. It gives you two voices, three LFO waveforms, and a blend knob that moves from dry sound to classic flanger to pitch vibrato. You will need to supply your own 9 V DC mains adapter to run it.
Pros
- Two flanger voices, Traditional and Complex & Notched, are selectable with a toggle
- Three LFO waveforms, Sine, Triangle or Random, shape the modulation
- Dry Flange Vibrato knob blends from completely dry signal to classic flanger to pitch vibrato
Cons
- Requires a 9 V DC mains adapter, which is not included
- Measures 121 x 66 x 41 mm and weighs 0.35 kg, so it takes up pedalboard space

How to choose the best chorus/flanger/phaser pedals
Tone Character
Walrus pedals rarely go for sterile perfection. They embrace a certain warmth and responsiveness, often with a slightly softened edge that's flattering to a wide range of guitars and amps. That 'fat midrange honk' you're chasing? Walrus often nails it, especially in their chorus and flanger offerings.
Modulation Depth & Rate Control
Their depth and rate controls aren't just linear sweeps. They often have a wider range, and the responsiveness feels more musical. You can dial in subtle shimmer or full-on psychedelic chaos without feeling like you're fighting the pedal.
Build Quality
Solid. Walrus uses quality enclosures, robust footswitches, and reliable components. They're built to withstand the rigors of gigging, and the knurled pots feel great under your fingers. It's not boutique-level 'over-engineered', but it's definitely a step above a lot of the cheaper options.
Versatility
While each pedal has its own distinct character, they're surprisingly versatile. The Julia chorus, for instance, can go from subtle Leslie-like swirl to a seasick wobble. This makes them adaptable to different genres, from clean country to heavy stoner rock.
User Interface & Controls
Walrus generally keeps things straightforward. The layouts are intuitive, and the controls are clearly labeled. They're pedals you can pick up and start experimenting with immediately, without needing to dive into a manual.
Buying guide
Alright, let's talk Walrus Audio chorus, flanger, and phaser pedals. They've carved out a serious niche for themselves - not just another boutique pedal company churning out variations on a theme. Walrus consistently delivers effects that feel like they've got character, a musicality that goes beyond just adding swirl. If you're looking for something that can add depth to your cleans, thicken your rhythm tones, or just inject some psychedelic weirdness, Walrus is a good place to start.
Walrus pedals aren't the cheapest out there, but you're paying for that extra bit of musicality and build quality. Don't expect ice-picky high-end clarity; their tone leans towards warmth. If you're running a bright amp and pickups, the Walrus warmth will be a huge benefit.
If you're chasing razor-sharp precision, maybe look elsewhere. Ultimately, it's about whether that signature Walrus vibe fits your overall sound.

Questions
How do Walrus pedals compare to MXR's chorus/flanger/phaser offerings?
MXR tends to be brighter and more aggressive, often with a more pronounced metallic edge. Walrus is warmer and more organic, with a more subtle and musical feel. It really depends on your taste and what you're trying to achieve.
Are Walrus pedals true bypass or buffered?
Most Walrus pedals are true bypass, but some models, like the Fathom Jr. flanger, feature a unity gain buffer. Check the specific pedal's specs before buying if that's a critical factor for your signal chain.
Can I use these pedals with a bass guitar?
Absolutely! While designed with guitar in mind, the Julia chorus and the MF-1A flanger are fantastic on bass, adding warmth and movement to low-end tones. Just be mindful of the rate settings to avoid muddiness.
Do I need a power supply?
Yes, Walrus pedals require a 9V DC power supply. They draw a decent amount of current, so a quality isolated power supply is recommended to avoid noise and ensure stable operation.
What's the difference between the Julia and the Bipolar?
The Julia is a lush, vintage-style chorus with a tape-like warble. The Bipolar is a more modern, stereo flanger with a wider range of modulation and a more intense effect. The Julia is the more subtle, versatile option.
