I believe there are no noticeable scratches or stains as it has only been used at home. Operation has been confirmed. There are no missing items, including the box. The following information is from Sound House: A model that can be called a representative of MAXON, the Pure Overdrive. It features a natural and warm distortion, excellent sound clarity, and good note separation. ■ Type: Guitar effect pedal ■ Overdrive ■ Power supply: 1 x 9V battery or AC adapter (sold separately) ■ Dimensions/Weight: 7W x 11D x 5.5Hcm, 280g ■ The natural distortion reminiscent of a vacuum tube amplifier directly expresses the original sound of the guitar and the player's style. When used as a booster, it will increase the gain comfortably without compromising the character of the amplifier.
