In the words of EarthQuaker Devices:

The Aurelius is not your run of the mill chorus pedal. This compact, beautifully cased wonder is a three voice chorus with six programmable presets and an expression control. Inspired by the 1970s CE-1 Chorus Ensemble pedal, this digital unit has been tirelessly tweaked and fine-tuned to give you an all-encompassing chorus and vibrato experience like nothing else.

By popular demand, Earthquaker has equipped the Aurelius with an expression control so you can use any TRS expression pedal to manipulate the Width, Rate or Balance.

Features:

• Chorus/Vibrato Mode: is a familiar traditional chorus type effect that leans towards vibrato with a triangle LFO modulating a short delay line
• Chorus/Flanger Mode: is a blend of chorus and flanger. It has more warmth and slower rates than Chorus/Vibrato Mode and uses a sine wave LFO to modulate the delay line.
• Rotary Mode: is a rotary chorus effect modeled after the sound of a Leslie speaker cabinet.
