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.
Gamechanger Audio Light Pedal User Manual
Determines the amount of signal being sent into the spring tank in all playing modes.
When turned all the way down there will be no reverb at all. Placing it at 12 o’clock is the safe bet. When maxed out, the spring tank will start gently breaking into distortion, as well as affecting the textures of all optical signals.
Gate is also a global parameter that affects both reverb outputs and all effect modes. When the Gate knob is at 12 o’clock it is neutral and does not affect the LIGHT Pedal’s sound.
To the left, all reverb is gated - the louder you play, the more reverb. As soon as the instrument’s signal stops, the reverb cuts out.
To the right, all reverb sounds are ducked - reverb levels are reduced in proportion to your playing dynamics.
Lets you choose a specific combination of optical sensors.
Each sensor combination will have a slightly different texture and timbral quality, as well as a different resonant frequency. As a general rule, moving towards the middle of the spring will produce warmer and richer reverb textures.
Sweep is a modulation mode that rhythmically scrolls back and forth through the different optical sensor pairs.
This is an optical tremolo mode, that turns the optical sensors on and off rhythmically. The tremolo effect can also apply to the spring tank output if the spring output (1) level is set equal to or higher than the optical output (2) level.
This mode is a lo-fi delay that will send the instruments signal back into the reverb tank several times
Feedback mode sets the spring tank into self-oscillation, which lets you create various drones and “wall-of-sound”-type distorted reverb pads. Lots of potential uses when paired with an expression pedal, or when in Momentary mode.
In harmonic mode the spring tank is driven by a special circuit designed to produce a lot of overtones and harmonics. Think of it as a shimmer reverb effect, but only produced naturally within the spring tank.
With TAILS switched ON, you will be able to smoothly turn the LIGHT Pedal off, while preserving the reverb’s natural decay trails. When switched OFF, the reverb trails will be cut as soon as the LIGHT Pedal is switched off.
When LATCH is ON the LIGHT Pedal’s footswitch will act as a standard latching on/off footswitch. When LATCH is OFF the LIGHT Pedal’s footswitch will act as a momentary effect switch
