The Ground FX Keto Double Chorus is a chorus pedal built by the German builder Ground FX that carries two chorus circuits in one enclosure. Each chorus can be switched on its own, so the pedal can run one voice alone or both together for a thicker, doubled modulation effect1.
What it does
The two choruses share a common set of Room, Delay and Volume knobs, which shape the overall character and level of the effect. Each chorus then has its own Rate and Depth controls, so the two voices can be set to different speeds and intensities. Separate footswitches let a player bring each chorus in and out independently1.
That layout means a player can set up, for example, a slow, shallow chorus and a faster, deeper one, and use either or both at will without re-tuning knobs between songs. It is a different approach from a single-voice chorus pedal, where one Rate and Depth pair serves the whole effect1.
