This is a Marshall guitar effects pedal from the 90s, made in the UK. When I purchased it used, the battery cover on the back was already missing and sealed with adhesive tape, so there are sticky tape marks. I tested it with a 9V adapter connected to a guitar amp, and it worked without any problems. I haven't tested it with batteries. It's a very old item, so there are some scratches and dirt, and some crackling in the knobs, but the switch is also in good condition. If you increase the gain and volume, it distorts well, more than you'd expect from an overdrive, and I think it can still be used for a long time. Thank you for your consideration. *No accessories included. This is a listing for the pedal only.*
