Walrus Audio Unveils the Polychrome Flanger

Walrus Polychrome Flanger

Walrus Audio is excited to round out their modulated offerings with the true bypass, all-analog Polychrome Flanger. Pulling in familiar layout controls from the Julia and Lillian, dial in a wealth of colorful flange with the D-F-V (Dry, Flange, Vibrato) blend knob and shape and voice switches.


Like the Iguana that's malleable to its environment, the Polychrome can blend into its surroundings for harmonious balance with subtle movement and texture or stand out with bold and vibrant confidence. For those that favor the dramatic, using the Voice Switch in the up position will give players a more complex, notched flange effect with less low end. Add in random LFO from the Shape Switch for new and unexpected sounds.


Walrus Audio Polychrome Analog Flanger Tech Demo

Resembling other members of the Walrus Audio modulation family, the Polychrome has a blend knob. The D-F-V (Dry, Flange, Vibrato) knob lets you blend the dry and delayed signal from full dry at minimum (no effect), to traditional flange at noon to full pitch vibrato at maximum. Don't sleep on the vibrato sounds in the Polychrome. Set the D-F-V knob to maximum, feedback to a minimum, and the voice switch up for some unique pitch vibrato.


Top-mounted input, output, and power jacks, as well as soft switch relay bypassing, make the Polychrome fit well on your board and ensures smooth operation for years to come.

Walrus Audio is offering The Polychrome for a retail price of $199 and is available now at walrusaudio.com and with our authorized dealers all over the galaxy.

The author found this one-of-a-kind tremolo/vibrato/sound-altering modulation box at Quattro Music Company in Thomas, West Virginia.

Producer and roots-guitar veteran Michael Dinallo pens his unabashed love letter to tremolo, with fond recollections of vintage Fender and Gibson amps, Dunlop’s TS-1, and a one-of-a-kind mystery modulator.

Tremolo is my favorite effect to modulate a guitar’s sound (and I love vibrato, too). I love it so much that it’s part of the moniker of the production team I had with the late Ducky Carlisle—the Tremolo Twins—as well as our Trem-Tone Records label. You might recognize Ducky from his many engineering credits, including Buddy Guy, or our work together on albums like Stax veteran Eddie Floyd’s heralded Eddie Loves You So, from 2008.

- YouTube

In our second installment with Santa Cruz Guitar Company founder Richard Hoover, the master luthier takes PG's John Bohlinger through the detailed (and scientific) process of analyzing, shifting and "tuning" the guitar's top before repeating the process when the back and sides are joined, and once again when introducing the neck to the instrument build while focusing on keeping everything harmoniously synergized and "tuned."
