The light Pedal is the Work of Teodors Kerimovs. As an engineer at Gamechanger Audio he wanted to create an anolog sound with something moving.
In a traditional springtank, reverb is created by turning the electrical signal of a guitar into mechanical energy at the springs. They vibrate as a speaker would and recreate, as best as they can, the original signal. This movement is again turned into electricity in a manner similar to how your guitar pick-ups capture the vibration of a guitar string.
With the Light Pedal, rather than recapturing the signal via an electromagnetic field, optical sensors detect the vibration as a change in light. The advantage to this is that it can be placed at multiple points in the spring capturing overtones that are otherwise lost via an electromagnetic field.
