The Light Pedal combines all the best features of a classic spring reverb with an innovative infrared optical sensor system and a unique effects section. Create countless new types of reverb textures that have never been possible before.

Incoming audio signal is converted into mechanical vibrations by an input transducer (a spring exciter). A similar transducer is used at the output stage to convert the spring's vibrations back into audio signal. Even a short impulse can cause extended vibrations – this is how the traditional reverb effect is achieved. Plate reverbs use the same principle to excite large, resonant sheets of metal.

However, due to energy dissipation, by the time vibrations travel along the length of the springs and reach the output transducer, most of the harmonic content of the input signal is lost, and the output is mostly composed of the spring’s own resonant frequencies. This is why all spring reverbs have a particular sound.
