Echo Cube is a dual delay inspired by the Cooper Time Cube, a rare analog unit that created echo using long coiled tubes instead of tape or electronic circuits. The delay time was defined by the physical travel of sound through air. Echo Cube recreates and expands this concept with two independent delay lines, each with time, feedback, and level controls. Choose between Time Cube for authentic hardware tone, or the experimental Garden Hose and Corrugated models for creative sound design. Flexible routing modes including serial, parallel, ping pong, mono sum, and mid side give you full control over delay interaction and stereo image shaping.
