The Moog EP3 is an expression pedal that is designed to work with any keyboard, synthesizer or pedal with an expression or CV input. The EP3 has a newly designed cam system and has an extremely smooth performance and durability. The polarity switch allows you to use this pedal with non Moog products. The EP-3 is built to withstand the rigors of daily abuse and touring, while providing the action and feel you need for precise, musical expression. When paired with Minifooger or Moogerfooger analog effects, the EP-3 unlocks new dimensions of sonic possibilities.
