Handmade Zendrive Clone For those who find the original too large and difficult to fit on a board. This one has slightly more gain than the original, a slightly different voice, and is otherwise well-made. I've used it extensively in live performances. The compact body is convenient to carry and designed to be easily installed even in limited spaces. Please understand that this is a handmade, compact pedal. Thank you. - Guitar Effects Pedal - Number of Knobs: 4 - Output Terminals: OUT - Input Terminals: IN - Power: 9V - Switch: Footswitch Thank you for viewing.
