EarthQuaker Devices Aurelius Tri-voice Chorus Pedal

Mode V: chorus/vibrato

Mode V is a traditional chorus powered by triangle LFO modulation. Turning the balance control clockwise reduces the dry signal while increasing pitch modulation levels. At max settings, Mode V becomes a pristine vibrato with extreme pitch-shifting presence.

Mode C: chorus/flanger

Mode C explores chorus and flanger together, treating them as close cousins within the modulation gang. Mode C pairs sine wave LFO modulation with noticeably slower and warmer rates than vibrato mode. Adjusting Aurelius’ width control in Mode C drastically changes the chorus/flanger interplay. Pushing the width past noon will introduce progressively more feedback for a thicker, more prominent flanger. Mode C is exceptionally versatile and fit for everything from jangly Britpop to crushing high-gain so long as you dial in the mix balance with care.

Mode R: rotary chorus

When maximum modulation is your goal, Mode R is the perfect pick. This rotary chorus effect modulates both amplitude and frequency. EQD studied genuine rotary chorus hardware dating back to the 1940s to ensure a motion-packed doppler effect that’s digitally exaggerated for easy use with guitar, bass, or your instrument of choice. Mode R’s key parameter is width: lower settings bring mids and lows (a true rotary’s woofer frequencies) to the fore. In contrast, higher width settings emphasize treble typically associated with a hardware rotary speaker’s horn.
