The LIGHT Pedal is the world’s first analog optical spring reverb system that uses infrared optical sensors.
This system is used to harvest the full timbral and harmonic range of the spring reverb tank. The LIGHT Pedal combines the best features of a classic spring reverb with the innovative optical sensor system and a powerful effects section. This combination opens up countless new types of reverb textures and sounds never heard before.
The LIGHT Pedal uses extremely sensitive optical sensors directed at different points of the spring. The optical sensors detect very subtle movements on the spring’s surface as sound-waves travel through it. This method allows to pick up a much wider range of frequencies, overtones and textures otherwise lost in the mechanical reverberation process. The optical sensors also open doors to effects that are new to spring reverbs, such as tremolo, modulation, feedback and added harmonics. The result is a wide variety of reverb sounds ranging from classic to experimental to pure magic.
The LIGHT Pedal’s user interface pushes the boundaries of spring reverb even further. The extended signal mix section allows for a very precise balance between the dry, classic reverb tone and the new and optical reverb signals. The ability to stack various effects and control them with playing dynamics or an expression pedal makes this pedal an advanced tool for sonic exploration.
THE CLASSIC SPRING TANK SOUND
The LIGHT Pedal’s central component and the main sound source is a traditional spring reverb tank, consisting of three major elements – the input transducer (spring exciter), the springs and the output transducer (pickup). There can be a lot of complexity in the spring’s movement patterns during the reverberation process, especially near the input transducer. However, due to the spring elasticity, by the time vibrations have reached the output transducer we mostly hear the spring’s own resonant frequencies, which is why all spring reverbs have such a particular jangly, metallic sound. The LIGHT Pedal’s spring output (the spring knob) offers a classic high-quality spring reverb sound with the option to adjust the spring “drip” (the drive knob) and the tone of the output signal (the tone knob).
THE OPTICAL SPRING REVERB SOUND
To capture the full range of the spring’s vibrations, the LIGHT Pedal uses multiple sets of special infrared optical sensors that act as photoelectric pickups. Each set of IR sensors is directed at a different point on the moving spring’s surface. The optical sensors detect much finer movements compared to the output transducer. This makes longer decays possible and more detailed frequency response, including subharmonics and overtones. Additionally, the pedal can achieve amazing modulation and tremolo effects by scrolling through the optical sensors or by switching them on and off (optical effects).
