I'm selling an effects pedal I recently purchased used, as I'm reorganizing my board. It can't be powered by a standard 9V 0.5mA adapter, so I'm including a dedicated power conversion cable that I purchased (around 900 yen on Amazon). You can use a regular effects pedal adapter with this cable. The DOD Overdrive Preamp/250 is a yellow effects pedal with two knobs for tone adjustment. I am also listing this on other sites, and will prioritize the first person to purchase. - Model Name: Overdrive Preamp/250 - Color: Yellow - Number of Knobs: 2 - Brand: DOD Thank you for looking.
