Gamechanger Audio Light Pedal - Optical Spring Reverb

Light Pedal

Light Pedal is the world’s first analog Optical Spring Reverb system that uses Infra-Red optical sensors to harvest the full timbral and harmonic range of a Spring Reverb tank.

It takes a lot of energy to transfer an audio signal across 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 will be lost converted into mechanical energy.

This is why spring reverbs have such a particular 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 regions of the spring to detect very nuanced 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 opens doors to some new effects types, 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.

• Sounds ranging from classic spring tank tones to colorful optical spring reverb tones with modulation and added harmonics.
• Separate level controls for the dry signal, spring and optical reverbs. The dry signal can be attenuated and boosted.
• 6 unique effects: optics (frequency and texture calibration), sweep (modulation), tremolo, reflect (delay), feedback and harmonic (added harmonics and octave tracking). Multiple effect stacking options.
• Drive knob for adjusting the signal level sent to the reverb tank, thus affecting the reverb tank’s behavior.
• Tone knob ranges from rumbling lows to piercing highs.
• Simple one-knob envelope control produces either gated or ducking reverb.
• Effects parameters can be linked to playing dynamics.
• Switchable reverb tails in bypass mode.
• Switchable latching or momentary modes for expressive playing.
• Assignable expression pedal input.
• Adjustable shock sensor to control spring noise produced by sudden movements, mechanical impact.
• Color LEDs inside the spring tank provide helpful visual feedback for monitoring the reverb’s output and input signal levels as well as multiple effects parameters, such as modulation rate.
• High quality buffered bypass.
• Powered by a standard 9V DC center negative power supply with at least 500 mA. The power supply is not included.
