This is as simple to use as it gets. This Chorus Effect Pedal is designed with just 2 controls: Rate and Depth. From this it's possible to create some amazing tonal effects as a stand alone or on board application. Using a shallow depth setting and a slower rate trill, the unit can produce a dreamy and pure choral tone with a near acoustic warmth. When increased to a wider depth setting a fast trill rate it can reach the sound of a crazy frenzy of voices. These are the extremes but it's possible to create every desired chorus effect in between.
