Photo Modulator Expression Controller

Death By Audio Photo Modulator

Let the light shine into your favorite pedals and devices to discover new tones with the Photo Modulator from Death By Audio, a photoresistor-based expression controller. This compact device plugs directly into any TRS expression input on pedals and other devices, providing a source of photo-resistive control from the onboard photocell. Changes in light amount reaching this element correspond to direct expression signals, enabling a wide range of unique expressive possibilities. Far beyond waving a foot at your pedalboard, you can use other light sources like strobes and flashlights to affect this controller, or even aim it at other LEDs on surrounding devices to create a cybernetic pedalboard organism. For these and any other bright ideas, check out the Photo Modulator from Death By Audio.
