【Super-Fuzz Effect Pedal】 I believe this is a rare model with a limited production run. I've only tested it for about an hour, and it's never been taken out of the house. From a pet-free and smoke-free environment. Functionality has been confirmed. Although the usage time is short, it is still a used item. Please understand that no claims or returns are accepted. - Model Name: Super-Fuzz - Brand Name: Tru-Fi - Power: 9V DC 2.1mm - Neg.Tip - Country of Manufacture: U.S.A. - Included Accessories: Original Box Thank you for looking.
