This MXR Distortion III Guitar Effects Pedal is part of a large collection of instruments and music equipment that belonged to my father, Ed Moon—a musician, educator, craftsman, and luthier. Please review the photos closely for the item’s overall cosmetic condition, included accessories, and any visible signs of use. We are currently cataloging hundreds of instruments and pieces of equipment from his collection, so we have not been able to fully test every item. This piece is being offered as-is based on the condition shown and the information available to us. That said, we are happy to perform reasonable testing or answer specific questions for seriously interested buyers whenever possible. Please feel free to reach out before purchasing if there is a particular function, connection, control, or detail you would like us to check. Inventory ID: EMGHH-412
