This is the BOSS OS-2 OverDrive / Distortion pedal. It has only been used at home and has never been taken outside. The exterior is in very good condition, with no noticeable scratches or scuffs. I think it's in pretty good shape for a used item. I've confirmed that it works. All knobs and switches are working without any problems. There was no crackling or malfunction. The OS-2 is a model that can continuously blend overdrive and distortion, and the DRIVE knob allows you to naturally control the quality of the distortion. It can handle a wide range of sounds, from light overdrive to edgy distortion, making it an easy-to-use pedal regardless of genre. The listing includes the pedal itself only. It will be carefully packed with bubble wrap before shipping. Please understand that the perception of the condition of used items can vary from person to person. Please check the photos and make your own judgment. I do not accept cancellations, claims, returns, or price negotiations after purchase.
