Gamechanger Audio’s Light Pedal Is Now Available for Purchase
March 2, 2021 · 7 sources
Gamechanger Audio announced that the Light Pedal, which it describes as the world’s first analog optical spring reverb system, was now available to order directly from its main site, priced at $349 in the US12. The first batch of one thousand units was being distributed to the backers who had supported the pedal’s crowdfunding campaign3.
The pedal is a true analog mono reverb built around a traditional spring tank: an input transducer excites the springs, and an output transducer picks up their vibration4. What sets it apart is a set of infrared optical sensors aimed at different points along the springs, acting as photoelectric pickups that read the springs’ motion directly4. As the maker puts it:
"The LIGHT Pedal is the world’s first analog optical spring reverb system that uses infrared optical sensors."4
Those sensors open up effect types the maker says are new to spring reverbs, including tremolo, modulation, feedback and added harmonics4. The pedal offers six effect modes, selected with a six-way knob and adjusted with a CTRL knob47:
| Mode | What it does |
|---|---|
| Optics | Choose a specific combination of optical sensors, each with a slightly different texture and timbral quality4 |
| Sweep | A modulation mode that rhythmically scrolls back and forth through the sensor pairs4 |
| Trem | A tremolo produced by rhythmically switching the sensors on and off4 |
| Reflect | A lo-fi delay that sends the signal back into the tank several times4 |
| Feedback | Sets the tank into self-oscillation for drones and wall-of-sound pads4 |
| Harmonic | Added harmonics4 |
The first three effects (optical, sweep, trem) can be stacked with one of the remaining three4.
The rest of the control set:
| Control | What it does |
|---|---|
| Dry / Spring / Optical mix | Three controls setting the levels of the dry, spring and optical signals; the dry signal can be attenuated or boosted4 |
| Drive | Sets the spring tank’s input level and its "drip"4 |
| Tone | Shared by the spring and optical sounds, from rumbling lows to piercing highs4 |
| Footswitch | Soft footswitch toggles bypass, with secondary functions for effects stacking, envelope control and footswitch assignment4 |
The Light Pedal draws 500 mA minimum at 9 V DC, center negative, through a 2.1 x 5.5 mm plug. There is no battery option and the power supply is not included, so plan for an isolated supply that can deliver its full current46.
