Purchased around 2019 and used several times. It was stored in an effects board after I quit the band in early 2022. The rubber feet on the back were removed and Velcro was attached to fix it to the effects board, so there are no noticeable scratches or stains. The Velcro has been removed, and the rubber feet that were stored have been reattached. Operation has been confirmed, and there are no problems in use. The box, instruction manual, and everything else that was included at the time of purchase are all still available.
