BOSS SD-1W overdrive pedal for guitar. I bought this as a spare when the price was reduced. I haven't used it since, so I'm selling it. Additional Information: * Authentic product purchased from Soundhouse on May 18, 2025. * I have confirmed that it works properly before listing. * Includes the pedal itself, the instruction manual, and the original packaging. There are no scratches or stains. Please feel free to ask any questions in the comments.
