When we use the term "chameleon-like," we're normally referring to something that fits into many different surroundings. But let's consider the transformation process: Have you ever watched a chameleon change colors? It's totally psychedelic. You could take a still photo and see that within each shift, there are many subtle variations, each of which are awesome. Now, imagine if this process were a guitar tone and you'll probably have a good idea what the Walrus Audio Polychrome flanger sounds like—solid modulation tones that sit comfortably within their surroundings while shifting in trippy, immersive, fun ways.
Shape and Soak Your Tone
The Polychrome's all-analog design gives users plenty of control for sculpting flange tones. The rate knob goes from extraordinarily slow to ridiculously fast. The depth and sweep controls are interactive and require practice to properly fine-tune, but ultimately yield tight, focused tones. The feedback control can be quite subtle or really drench your sound. A 3-way shape switch allows you to select between sine wave, triangle wave, or a random LFO wave. I enjoyed all of them, though I generally stuck with the most predictable options. A 2-way voice switch selects between a wide frequency range and a mid-focused notched sound. A dry-flange-vibrato blend control—labeled "D-F-V"—goes from completely dry to completely wet. At some totally soaked settings, I perceived a little volume drop, but the effect is still totally usable. The soft-relay switch, by the way, features momentary functionality when you hold it down. Jacks are top-mounted.
"At slower rates and high feedback settings, I discovered a gooey, underwater- sounding version of the old whooshing jet-flange effect that was the Polychrome's most warped and unique sound."
Plenty of Floyd and Sco, Fewer Airplanes
While the Polychrome offers a wide pallete of sounds, it excels at subtlety. Rather than just favor the noisy, brutish airplane sounds I associate with the flangers of my youth, this pedal excels at adding a warm neon glow without ever getting harsh. Once you get the hang of the controls, you can summon just about any flanger tone you could want, as well as excellent phaser- and chorus-like tones.
With so much range in each of the controls, it's no surprise that I worked primarily within the middle-range of the rate, depth, and sweep knobs. There, I found Gilmour-style goodness that shone like a crazy diamond. At slower rates and high feedback settings, I discovered a gooey, underwater-sounding version of the old whooshing jet-flange effect that was the Polychrome's most warped and unique sound. I could easily imagine zoning out on this vibe all day long. At the other end of the rate knob, hip '90s-Scofield faux-Leslie-style tones had me clinking out funky ii-V chord vamps to no end. If funky organ jazz was my gig, I'd have this on constantly.
The Verdict
If you're looking for a modulation pedal that delivers everything from subtle always-on style tones to totally submerged flange sounds, the Polychrome covers it all. The pedal's analog circuit offers plenty of organic warmth and extensive control. Sure, it eschews some of the noisier sounds of classic flangers, but I'd argue that the extra flexibility means you'll probably use it more often than your old jet-whooshing standby.

The Texan rocker tells us how the Lonestar State shaped his guitar sounds and how he managed to hit it big in Music City.
Huge shocker incoming: Zach Broyles made a Tube Screamer. The Mythos Envy Pro Overdrive is Zach’s take on the green apple of his eye, with some special tweaks including increased output, more drive sounds, and a low-end boost option. Does this mean he can clear out his collection of TS-9s? Of course not.
This time on Dipped in Tone, Rhett and Zach welcome Tyler Bryant, the Texas-bred and Nashville-based rocker who has made waves with his band the Shakedown, who Rhett credits as one of his favorite groups. Bryant, it turns out, is a TS-head himself, having learned to love the pedal thanks to its being found everywhere in Texas guitar circles.Bryant shares how he scraped together a band after dropping out of high school and moving to Nashville, including the rigors of 15-hour drives for 30-minute sets in a trusty Ford Expedition. He’s lived the dream (or nightmare, depending on the day) and has the wisdom to show it.
Throughout the chat, the gang covers modeling amps and why modern rock bands still need amps on stage; the ins and outs of recording-gear rabbit holes and getting great sounds; and the differences between American and European audiences. Tune in to hear it all.

Guest picker Carmen Vandenberg of Bones UK joins reader Samuel Cosmo Schiff and PG staff in divulging their favorite ways to learn music.
Question: What is your favorite method of teaching or learning how to play the guitar?
Guest Picker - Carmen Vandenberg, Bones UK
The cover of Soft, Bones UK’s new album, due in mid-September.
A: My favorite method these days (and to be honest, from when I started playing) is to put on my favorite blues records, listen with my eyes closed, and, at the end, see what my brain compartmentalizes and keeps stored away. Then, I try and play back what I heard and what my fingers or brain decided they liked!
Bone UK’s labelmade, Des Rocks.
Obsession: Right now, I am into anyone trying to create sounds that haven’t been made before—bands like Queens of the Stone Age, Jack White, and our labelmate, Des Rocs! There’s a Colombian band called Diamanté Electrico who I’ve been really into recently. Really anyone who’s trying to create innovative and inspiring sounds.
Reader of the Month - Sam C. Schiff.
Sam spent endless hours trying to learn the solo Leslie West played on “Long Red,” off of The Road Goes Ever On.
A: The best way to learn guitar is to listen to some good guitar playing! Put on a record, hear something tasty, and play on repeat until it comes out of your fingers. For me, it was Leslie West playing “Long Red” on the Mountain album, The Road Goes Ever On. I stayed up all night listening to that track until I could match Leslie’s phrasing. I still can’t, no one can, but I learned a lot!
Smith’s own low-wattage amp build.
Obsession: My latest musical obsession is low-wattage tube amps like the 5-watt Fender Champ heard on the Laylaalbum. Crank it up all the way for great tube distortion and sustain, and it’s still not loud enough to wake up the neighbors!
Gear Editor - Charles Saufley
Charles Saufley takes to gear like a duck to water!
A: Learning by ear and feel is most fun for me. I write and free-form jam more than I learn other people’s licks. When I do want to learn something specific, I’ll poke around on YouTube for a demo or a lesson or watch films of a player I like, and then typically mangle that in my own “special” way that yields something else. But I rarely have patience for tabs or notation.
The Grateful Dead’s 1967 debut album.
Obsession: Distorted and overdriven sounds with very little sustain—Keith Richards’ Between the Buttons tones, for example. Jerry Garcia’s plonky tones on the first Grateful Dead LP are another cool, less-fuzzy version of that texture.
Publisher - Jon Levy
A: I’m a primitive beast: The only way I can learn new music is by ear, so it’s a good thing I find that method enjoyable. I’m entirely illiterate with staff notation. Put sheet music in front of me and I’ll stare at it with twitchy, fearful incomprehension like an ape gaping at the monolith in 2001: A Space Odyssey. I’m almost as clueless with tab, but I can follow along with chord charts if I’m under duress.
The two-hit wonders behind the early ’70s soft-rock hits, “Fallin’ in Love” and “Don't Pull Your Love.”
Obsession: Revisiting and learning AM-radio pop hits circa 1966–1972. The Grass Roots, Edison Lighthouse, the Association, the Archies, and Hamilton, Joe Frank & Reynolds—nothing is too cheesy for me to dissect and savor. Yes, I admit I have a serious problem.
Diamond Pedals introduces the Dark Cloud delay pedal, featuring innovative hybrid analog-digital design.
At the heart of the Dark Cloud is Diamond’s Digital Bucket Brigade Delay (dBBD) technology, which seamlessly blends the organic warmth of analog companding with the precise control of an embedded digital system. This unique architecture allows the Dark Cloud to deliver three distinct and creative delay modes—Tape, Harmonic, and Reverse—each meticulously crafted to provide a wide range of sonic possibilities.
Three Distinct Delay Modes:
- Tape Delay: Inspired by Diamond’s Counter Point, this mode offers warm, saturated delays with tape-like modulation and up to 1000ms of delay time.
- Harmonic Delay: Borrowed from the Quantum Leap, this mode introduces delayedoctaves or fifths, creating rich, harmonic textures that swirl through the mix.
- Reverse Delay: A brand-new feature, this mode plays delays backward, producing asmooth, LoFi effect with alternating forward and reverse playback—a truly innovativeaddition to the Diamond lineup.
In addition to these versatile modes, the Dark Cloud includes tap tempo functionality with three distinct divisions—quarter note, eighth note, and dotted eighth—ensuring perfect synchronization with any performance.
The Dark Cloud holds special significance as the final project conceived by the original Diamondteam before their closure. What began as a modest attempt to repurpose older designs evolved into a masterful blend of the company's most beloved delay algorithms, combined with an entirely new Reverse Delay setting.
The result is a “greatest hits” of Diamond's delay technology, refined into one powerful pedal that pushes the boundaries of what delay effects can achieve.
Pricing: $249
