EarthQuaker Devices’ newest pedal, the Aqueduct Vibrato, is a pitch-shifting enigma that just emerged from the watery depths, sending the High Council of Tone into a frenzy. Are its intentions good or evil? Are its eight modes of vibrato meant to bring peace to the Planet Ohio, or to destroy it from within and defile the very nature of Tone? Watch the video above to find out.
Contrary to what’s written on the faceplate of certain famous deluxe amplifiers, vibrato is a form of frequency modulation which we hear as a variation in pitch, whereas tremolo (the effect you hear on such amps) is change in volume, caused by amplitude modulation. The EarthQuaker Devices Aqueduct firmly plants itself in the vibrato category and is capable of everything from gently rolling pitch wobbles to downright unsettling, randomly generated waveform warps.
The Aqueduct’s eight modes — Sine, Triangle, Ramp, Square, Random, Env D, Env R, and Env P — add up to make it an extremely versatile tool. From the musical, amp-like vibrato of Sine mode to the shoegaze-friendly pitch modulation of the Env P mode, there’s a sound for every playing situation.
