Positive Grid Cloner Chorus pedal is available under the Mod effect group and is inspired by the Electro Harmonix Small Clone.
What Electro Harmonix says:The classic chorus! Analog chorus pedal popularized by Kurt Cobain. The finest analog chorus sounds: from clear, rich and dimensional to warm pulsating warbles, can be intensified with the Depth Control. Simple tweaks generate exciting doubling effects. Chiming 12-string tone, or Leslie-like warbles.
