Gamechanger Audio LIGHT Pedal

Gamechanger Audio's Light Pedal is a spring reverb that integrates infra-red optical sensors in order to take full advantage of the range of timbral and harmonic characteristics of a real spring reverb. Much of what you think of as the spring reverb sound is the intrinsic resonant frequencies of the spring's physical structure—transferring an audio signal into a spring dissipates much of that original signal into mechanical energy. The Light Pedal uses optical sensors, carefully lined up along the spring's length, which detect minuscule changes in the spring's movement. This takes full advantage of the range of sounds and timbres made possible by the reverberation process. Not only that, but it opens up new realms of possibilities in terms of what effects are possible using a spring reverb, including optical harmonic shimmer, optical reverb modulation, and optical reverb tremolo.

Control the level of the spring tank, optical sensors, and the dry signal going into the pedal. Adjust the amount of signal passing into the reverb tank using the drive control. The pedal will begin to distort the incoming signal at the highest settings, which you may want or not. Sculpt the pedal harmonics using the tone control to accentuate or filter the harshness of the pedal. The envelope adjusts the reverb dynamics from sudden gated reverb to wide open and full sounding reverb. Select between six effects types using the rotary control; optics, sweep, trem, reflect, feedback, and harmonic. The dedicated ctrl knob controls a relevant parameter in each effects mode, from the optical sensor's position to modulation LFO speed to feedback amount and spectral range. Use the latch switch to turn the Light Pedal into a momentary effect, with the bypass switch only letting sound through if pressed down. A built-in shock sensor turns off the audio signal when it detects mechanical impact with three sensitivity levels. Turning it off lets you rattle and bang on the pedal to get the thunderous sound of a moving spring reverb.

Like many of the other GameChanger Audio's products, the Light Pedal represents a new paradigm in effects. The unique implementation of a radical new idea is what they're all about, and they deliver with this pedal.

Turning Reverbs into HARSH Instruments with Feedback
Manipulating feedback loops is one of the most interesting ways to explore sound, and reverb is one of the most evocative effects for placing sounds in space. Thus, curious minds are certainly wondering: what happens when you use reverb effects with feedback techniques?

In this video, Jacob gives a rundown of some of his favorite ways to use reverb pedals in feedback loops, and allowing the effect to become an instrument in itself. Touching on topics like no-input mixing, adding Eurorack modules to the mix, and strange convolution, this video aims to serve as a springboard for trying out reverbs of all kinds in ways you might not expect.

Specifically, we highlight these tricks with the Red Panda Context, the Strymon Night Sky, the Gamechanger Audio Light Pedal, and the Poly Effects Beebo, but we encourage you to try these patches with any and all reverbs you might have hanging around the studio. After all, this video is all about experimentation, and these ideas are meant to be explored, expanded upon, and inviting you to embark on new sonic journeys.
