WALRUS AUDIO Julia Chorus and Vibrato PedalDesigned for electric guitarists and bass players, the Walrus Audio Julia is an analog chorus and vibrato pedal capable of anything from mild chorusing effects to woozy, wacky vibrato. The pedal provides controls over the rate of the effect, as well as its depth. A lag knob is on hand to dictate a delay time, which in turn affects the LFO. This control fosters experimentation in a manner not usually found on analog chorus pedals.
