The Gamechanger Audio Light Pedal Optical Spring Reverb System is the world’s first analog optical spring reverb system that uses infrared optical sensors to capture the full timbral and harmonic range of a spring reverb tank.

It takes a lot of energy to transfer an audio signal along the length of a vibrating spring. By the time the source audio signal reaches the spring tank’s output transducer, most of its nuanced harmonic content has been lost, converted into mechanical energy.

This is why spring reverbs have such a distinctive sound, since what you end up hearing is largely the spring’s own resonant frequencies. The Light Pedal uses extremely sensitive optical pairs, placed at specific points along the spring to detect very subtle movements on the spring’s surface as sound waves travel through it.

This method opens up a much wider range of frequencies, harmonics, overtones, and textures that are otherwise lost in the mechanical reverberation process. Using optical sensors also enables new types of effects, such as optical reverb tremolo, optical reverb modulation, and optical harmonic shimmer.

The result is a wide variety of analog reverb sounds ranging from classic to experimental to pure magic.
