Gijs SK-1 Mechanical Glitch Mod


There is nothing quite as mesmerizing as watching the patch arm of this mechanical-electric Casio SK-1 go round and round, like a chu-chu train leaving the glitch station. The Gijs’ SK-1 device has bends patched to various places around the stationary contact wheel and while the arm twists around at various revolution rates glitches are triggered. The keyboard also has a custom PCB that controls the Pitch and Internal Clock Speed which is done through the use of an opto-transistor. Definatelly one of a kind mod, great work. Thanks to Karl and Gij’s for sending this in. More images on Gijs’ website.
