Green effects pedal with volume, tone, and drive adjustment functions. - Model Name: TUBE DRIVE V1 - Color: Green - Functions: Volume, Tone, Drive adjustment - Connectors: Input, Output jacks - Power: DC 9V adapter Thank you for viewing. This is a guitar effects pedal I found at my parents' house. I have confirmed that it produces sound. There are some scratches from use. I am not sure about the sound quality or how it feels to use. My family cherished this, so I would like to pass it on to someone who will continue to use it. #MintAmp I am also selling other effects pedals! I will pack it carefully and ship it! ✨
