Please be aware that there are considerable scratches and dirt. One screw is missing. This is a Fulltone OCD overdrive pedal. I bought it 5 or 6 years ago, so I don't remember the version. There is a serial number inside, but I couldn't make it out. I used it a lot in live performances, so there are many scratches. There are no issues with the operation. I am not planning to lower the price at this time. Thank you for your understanding.
