EarthQuaker Devices' new Aqueduct Vibrato is a pitch-shifting stompbox that can bring all manner of warp and wobble to your tone. The Aqueduct comes with eight different modulation settings, offering a variety of vintage-style vibrato and newer, synthier pulsations. The Envelope-Controlled Pitch mode—or, as EQD has internally nicknamed it, "the My Bloody Valentine setting"—adds a bit of chorus and flanger to vibrato-arm-like pitch shifts to approach MBV's swirling, undulating sounds.
