Thank you for viewing! This is a self-made clone pedal of the Lovepedal COT 50. It has excellent responsiveness to volume and picking. When turning the BIAS knob, there is a sound like scratchy noise, but it seems to be the same specification as the original clone. There is no problem for normal use. Made with P to P wiring on a universal board. Center knob: BIAS Right jack: IN Left jack: OUT Power can be supplied by a center-negative 9V adapter or a 9V battery (batteries are not included). Includes: 1 pedal (no other accessories) - HAMMOND 1590B, shrink-wrapped white powder coating (case size 111mm x 60mm x 31mm) - Capacitors use high-quality components. - Solder: Kester 44 - Variable resistor: alpha - Foot switch: alpha - Phone jack: Marushin Musen Denki - Tested and confirmed to be working properly before listing. All knobs and switches function without problems, and there are no issues such as scratchy noise or sound dropouts. There are minor scratches on the side and back cover of the case from when it was purchased, but they are not very noticeable. - Returns are not accepted for reasons other than physical damage upon arrival that prevents the pedal from producing sound. - This is a handmade product, so returns based on the buyer's subjective opinions, such as "it's not what I expected" or "I don't like it," are not accepted.
