This is a cool and cute overdrive & fuzz pedal. It's a rare item that is not currently available on the market. It's being sold as junk because it has operational issues. The condition is as follows: It seems to be receiving power from both a battery and a DC adapter, but basically, no sound comes out when going through this unit. Furthermore, it has two channels (drive/fuzz), but: Drive: Lights up and doesn't light up, unstable Fuzz: Lights up Please understand that this is a junk item, and those with knowledge of repairs are kindly requested to purchase it. - Model Name: OD-Fuzz - Brand Name: Black Cat - Control Knobs: Drive, Volume, Fuzz - Input/Output Terminals: Input, Output, DC Jack - Serial Number: #338 Thank you for looking.
