Thank you for viewing. Overall, the item shows little signs of use, but the paint has peeled along the tape due to the Velcro that was attached to the back. It doesn't affect its functionality, but some people may be concerned. The operation itself should be fine. I checked the input/output and the effects for this listing. Operation has been confirmed with both a 9V battery and an AC adapter. There are some scratches that are difficult to see in the photos, so please consider purchasing this item with the understanding that it is a used item. Immediate purchase is welcome. I will ship it on the same day of purchase, or at the latest, the next day. Thank you.
