The DigiTech Nautila Digital Chorus Flanger Pedal opens up a sea of morphing, undulating tones easily navigated through a streamlined interface and intuitive design. Choose between Chorus and Flange modes and then toggle between eight and four respective unique modes by tweaking wave shape (Drift knob) and the Voice knob, which operates as a Tone control for chorus and a Regen for the flange. Another revolutionary offering from a company that's staked its place on the vanguard of the effect world, this pedal is a welcome addition to experimental boards or a handy addition for synth fans.
