Multi-effects processor GT-10 Purchased about 15 years ago, and has been stored unused at home for the last 5 years. There are scratches and dirt from use. In the third photo, the power switch is missing, and you need to use your little finger to press the switch deep inside to turn it on. (It does turn on) Also, since detailed operation has not been confirmed, it will be considered as junk. Accessories include an AC adapter, instruction manual, and box (with dedicated packing material). The box also has tape and scratches from shipping. Please understand. When shipping, please ship in the condition of the box in the photos. (I will wrap it simply in plastic, but please understand that it is amateur packing) When purchasing, please confirm the above and no claims and no returns will be accepted. Manufacturer...BOSS
