Earthquaker Devices Aurelius Tri-Voice Chorus Pedal

The EarthQuaker Devices Aurelius is far more than your average chorus pedal. This compact yet powerful unit combines three chorus-based effects — Vibrato, Chorus, and Rotary — with six programmable presets and expression control, delivering a versatile modulation platform for creative players.

Inspired by the legendary 1970s CE-1 Chorus Ensemble, the Aurelius refines and expands the concept with modern digital precision and flexible control options. Whether you’re after lush, swirling chorus, subtle pitch modulation, or rotating-speaker-style tones, Aurelius offers a world of sonic possibilities in a beautifully designed, pedalboard-friendly format.

A Chorus Pedal Like No Other

The Aurelius goes beyond traditional chorus pedals with a three-voice modulation engine that lets you seamlessly shift between Vibrato, Chorus, and Rotary modes. Each mode responds dynamically to your playing and can be customised through Width, Rate, and Balance controls, allowing you to create tones ranging from shimmering modulation to seasick vibrato and rotating-speaker swirl.

Unlike vintage units, the Aurelius offers six user presets, enabling instant access to your favourite settings on stage or in the studio. Simply tap the Preset (“Save/Recall”) switch to store or retrieve your saved configurations, including control positions, mode selection, and expression pedal assignments.

Expression & Control Versatility

With expression pedal or control voltage (CV) capability, Aurelius opens up new levels of interactivity. Use any standard TRS expression pedal to take control over Width, Rate, or Balance — and save unique assignments per preset. The EXP input also accepts CV signals ranging from 0–3.3V, giving you modular-style control over your modulation depth and speed.
