The Kraakdoos, also known as the Cracklebox, is an experimental electronic musical instrument first developed by Michel Waisvisz in the 1970s. This device makes interacting with electronic circuits fun and unconventional, and is played through its touch-sensitive surfaces. When you complete the circuit with your fingertips, it starts producing sound, with the tone, intensity, and rhythm changing according to your touch.

This modern version designed by Vaemi presents the classic Cracklebox concept with an innovative approach. The Kraakdoos serves as a creative tool in sound design, appealing to both musicians and those interested in experimental sounds.

The Kraakdoos, aka Cracklebox, uses the classic LM709 op-amp, which is now only available from a limited number of manufacturers. This component plays a crucial role in shaping the device’s characteristic tone and unique sound palette, providing a truly one-of-a-kind audio experience.
