Operation confirmed. A Decksaver is included as a bonus. One owner. Used at home. Non-smoking, no pets. No scratching performed. There are no major scratches on the exterior, but there may be minor scratches due to aging if you look closely. There are no problems with use, but the CH1 LOW knob has some damage as shown in the photo. The LOW knobs for CH1 and 2, which were used frequently, are a little lighter compared to the other knobs.
