EarthQuaker Devices Aurelius Tri-Voice Chorus

The EarthQuaker Devices Aurelius Tri-Voice Chorus is a chorus pedal that defies convention. This compact marvel goes beyond the ordinary, offering a three-voice chorus with six programmable presets and expressive control. Distinguished by Vibrato Mode, Chorus Mode, and Rotary Mode, Aurelius allows you to craft a personalized sound universe. Manipulate Width, Rate, and Balance effortlessly, seamlessly transitioning between modes to curate a unique blend.

Inspired by the iconic 1970s CE-1 Chorus Ensemble pedal, this digital innovation has undergone meticulous tweaking to deliver an unparalleled chorus and vibrato experience. Responding to popular demand, an expression control has been added, allowing the use of any TRS expression pedal to modulate Width, Rate, or Balance. In Vibrato Mode, experience a subtle chorus with a touch of seasick vibrato, effortlessly alternating between the two.

The possibilities are limitless, offering a versatile range of tones and effects. With a simple tap of the Preset ("Save/Recall") switch, access up to six customized settings instantly. This pedal seamlessly blends '70s nostalgia with cutting-edge technology, providing a chorus journey like never before. 

Controls:

• Vibrato:

• This mode is a familiar traditional chorus type effect that leans towards vibrato with a triangle LFO modulating a short delay line. When the Balance control is turned fully clockwise, the dry signal is removed and the effect becomes a pitch vibrato.

• Width
  Controls the amplitude of the LFO and determines how wide the pitch modulation will sweep.

• Rate
  Adjusts the speed of the LFO.

• Balance
  In Mode V, the Balance control adjusts the amount of pitch modulation that is blended in with the dry signal. When the Balance control is turned fully clockwise, the dry signal is removed and the effect becomes a pitch vibrato.

• Chorus:

• Mode C is a blend of chorus and flanger. It has more warmth and slower rates than Mode V and uses a sine wave LFO to modulate the delay line. The Width control plays a major role in this mode and determines which type of modulation is more prominent.

• Width
  Controls the amplitude of the LFO and determines how wide the pitch modulation will sweep. Higher Width settings have a more pronounced flanging effect. When the Width control is turned past the center point, feedback is gradually added and makes the flanging effect more prominent.

• Rate
  Controls the speed of the LFO.

• Balance
  In Mode C, the Balance control adjusts the level of the modulated signal. Turn clockwise for a more pronounced effect.

• Rotary: 

• Mode R is a rotary chorus effect modeled after the sound of a Leslie speaker cabinet. This effect combines both amplitude and frequency modulation for a Doppler effect.

• Width
  Controls the amplitude of the LFO and determines how wide the pitch modulation will sweep. Lower settings accentuate the lower “woofer” frequencies and higher settings accentuate the upper “horn” frequencies.

• Rate
  Controls the speed of the LFO.

• Balance
  In Mode R, the Balance control adjusts the wet/dry balance of the signal. Turn clockwise for a more pronounced and pulsing sub frequency effect.
