Thank you for viewing. This is the BOSS standard distortion pedal, the "MT-2 Metal Zone." I purchased it over 10 years ago and only used it a few times, storing it at home since then. I haven't confirmed its operation, but the storage environment was good, and there are no major scratches or stains. There are no accessories, and the item is only the main unit. Please consider this item with the understanding that it is a used item and has been stored for a long time. It's a popular model, so please consider it at this opportunity. - Model: Metal Zone MT-2 - Brand: BOSS - Function: Equalizer adjustment (LOW, MID, HIGH) - Power: 9V battery or AC adapter
