Aurelius Tri-Voice Chorus Video Manual | EarthQuaker Devices

Hello EarthQuakers! Meet the Aurelius Tri-Voice Chorus! EQD President and Product Designer Jamie Stillman sits down and gets into the nitty gritty about our newest device.

This compact, beautifully cased wonder is a three-mode chorus with six programmable presets and expression control. Choose from Vibrato (V) Mode, Chorus (C) Mode, and Rotary (R) Mode and manipulate their Width, Rate, and Balance to achieve your ideal sound. Shift seamlessly from one mode to another to cop a blend that is all your own. Just one simple tap of the Preset (“Save/Recall”) switch and you can summon up to six settings of your choosing at will.

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.

Jamie says, “I wanted to take what inspired me in the CE-1 and put it in the Aurelius, but exaggerate the parts that I felt were lacking. Each of the voices in the Aurelius was designed to be its own standalone effect, so the balance, rate, and width have different parameters on each voice.”

We even took it way back to the 1940s and the advent of the Leslie speaker to boldly capture the sound of its rotating baffle system for the Rotary mode. We studied the way that the horn and the rotor moved on Leslie speakers and emulated the phasing and speeds of the low frequency oscillator, but we exaggerated the hell out of them to make it sonically suitable for guitar, bass or your instrument of choice.

The 3 modes are:

Mode V: Chorus/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.

Mode C: Chorus/Flanger
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.

Mode R: Rotary Chorus
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.

And by popular demand, like many of our pedals, we’ve equipped this with an expression control so you can use any TRS expression pedal to manipulate the Width, Rate or Balance. Put it in the Vibrato mode and you’ll have a really subtle chorus with a seasick vibrato and alternate quickly between the two seamlessly.

Each and every Aurelius is hand crafted in Akron, Ohio, USA and is inspected by the spirit of speaker innovator Donald Leslie.
