The Boss DS-1 Distortion is an effects pedal that was possibly used by Prince in the 1980s. Susan Rogers has mentioned Prince using an orange distortion pedal in the studio with his Linn LM-1 drum machine. There is a possibility it was used as a guitar effect around this time.
Brownmark used a distortion pedal on songs like Computer Blue, and it is possible that it was a Boss DS-1. An orange pedal can be seen in the Manic Monday video. It was also used by Dez Dickerson.
