What Does a Chorus Pedal Do?


Six highly customizable modulation programs





The M1 is a veritable modulation workstation, with six modulation programs that each contain three unique types:





Chorus: Type 1 is a classic lush '80s chorus sound, while Type 2 adds in a second chorus with offset rate and depth. The third type is a tri-chorus effect that runs all three choruses in parallel for wild spacey tones.





Phaser: The first type is a 2-stage phaser with a single notch. Type 2 doubles those parameters for a much more powerful effect; Type 3 is modeled after the classic Uni-vibe sound.





Tremolo: Type 1 is a traditional trem that’s similar to classical optical and bias trem sounds. Type 2 is a harmonic tremolo setting that raises and lowers your high and low frequencies opposite of each other. The third type functions according to several predefined rhythmic patterns for a pulsing tremolo effect.





Vibrato: The first type is similar to Walrus Audio’s Julia and Julianna pedals in the “V” mode ? more classic vintage vibrato sounds. Type 2 is inspired by old record player modulation, while Type 3 is based on the wow and flutter found in old tape delay units.





Rotary: This mode captures the classic rotary speaker effect, with Type 1 as a traditionally standard watery spinning sound. Type 2 is just the horn spinning and sound playing of of the drum, while Type 3 reverses this with sound from the horn and a spinning drum.





Filter: Type 1 is a lowpass modulated filter sound that’s perfect for darker tones, while Type 2 functions as a highpass filter. Type 3 is a full bandpass filter that forms a “sliding window” of frequencies.





The X factor





Each one of the M1’s six programs features a special “X” setting via the tune knob that controls a special effect-specific parameter:





Chorus: Adjusts the maximum level of pitch detuning.





Phaser: Adds feedback, producing a more dramatic tone.





Tremolo: Changes the phase of the left and right volume modulation, resulting in an ultra-wide stereo pan sound.





Vibrato: When using Type 1 and 2, this setting adjusts the phase of the vibrato’s pitch modulation when connected with stereo outs. In Type 3, it controls the amount of flutter.





Rotary: Adjusts the drive of the horn.





Filter: Changes the filter’s resonance, resulting in a more in-your-face tone.





Powerful, stage-ready MIDI capability





The Walrus Audio M1 includes nine onboard preset slots. What’s more, up to 128 presets are accessible via MIDI, which makes this modulation stompbox an excellent choice for complex, pro-level live rigs. The onboard presets are readily accessible via the bank switch, and you can cycle between them by pressing Bypass and Tap simultaneously. The pedal’s Tap LED gives you an at-a-glance confirmation of which preset you’ve selected ? changing from red to green to blue. And any adjustments you make will change the LED to purple to show that you’ve edited the preset. This extensive preset management makes the M1 a truly gig-worthy effects pedal.





Walrus Audio pedals: built by sound tweakers for sound tweakers





The artists, musicians, and engineers at Walrus Audio take pleasure in chasing sounds that inspire, like the perfect breakup of an overdrive, a beautifully thick distortion, an endlessly sustaining reverb, and a self-oscillating delay. Simply put, these guys love to play with sound. They design stompboxes that re-create the sonic textures that they hear in their heads. Built by tone tweakers for tone tweakers, Walrus Audio’s guitar pedals are as versatile as they are functional. Complete with eye-grabbing graphics, Walrus Audio’s pedals are the perfect tools for guitarists who want to sculpt their own unique sounds.
