The ERD (Earth Return Distortion) modular Eurorack series seeks to literally “put the earth back into circuit with technology.”

Based on the logic that all electricity travels through the earth, and electronic circuitry devices are extracted from the earth, the ERD sends control and audio signals through a small block of soil, yielding distorted and amplified sound. The jack can also be switched out to route through “local earth piles and forest sites” instead. It’ll be available in limited quantities here.
