This is a early 1980s MXR Distortion + that was made in the USA. Included with the pedal is its original box. This specific pedal was modified by Alchemy Audio in March of 2019. They added the DC Power Jack, added a Red LED, installed a 3PDT Footswitch button, and wired it for true bypass. The pedal is fully functioning and sounds great. Cosmetically, this pedal shows off that it was somebody's go-to for a long time. It has a Mooer Footswitch topper on it to make hitting the switch easier.
