think of sound as color.

$150

color theory invites you to explore a new spectrum of tonal possibilities.

color theory is an all-analog parallel processor available in eight different colors. it allows for two send/return loops to be mixed in parallel with an added phase inversion switch. with color theory, pedal combinations become primary, secondary, and tertiary shades of sound.

  • knob: loop adjustment

  • toggle: phase inversion

  • standard negative center 9v

  • quiet op-amps
