EarthQuaker Devices Aurelius Three Mode Chorus Pedal

Time to get swirly! This three-mode chorus pedal offers a multitude of magical sounds, ranging from traditional, lush chorus to otherworldly whirlpools.

Welcome, fellow frequency chaser! Thinking of embarking on a magical journey with the mighty Aurelius pedal? Pause that handmade gnocchi tutorial video for just a moment and open your mind to the powers of this majestic three mode chorus.

You see, this is not simply your run of the mill chorus pedal. This compact, beautifully cased wonder is a three-mode chorus with six programmable presets and an 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) and you can summon up to six settings of your choosing at will.

Get swirly with Justin as he takes the EarthQuaker Devices Aurelius for a spin:

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. EarthQuaker Deviceseven 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. EarthQuaker Devices 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 EarthQuaker Devices exaggerated the hell out of them to make it sonically suitable for guitar, bass or your instrument of choice.

And by popular read more demand, like many of EQD's pedals, EarthQuaker Devices has 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. And that's only just one mode. The possibilities are endless. Think about it.

This compact world of chorus in a box will fit on any pedalboard and is so intuitive and easy to use that you most likely won't have to listen to us yappin' away about it ever again.

Each and every Aurelius is hand crafted in Akron, Ohio, USA.

This pedal is killer. The versatility is hard to express fully. The Aurelius goes from flanger to classic chorus to full-on vibe at the twist of a knob. The preset function is a godsend, and the ability to quickly switch back to live settings really expands the impromptu versatility. Seriously, I cannot recommend this pedal enough.
