Prince

When it comes to effects, Prince seemed to like Boss Pedals. While it very well could be that Prince owns the entire Boss line of effects, he was commonly seen with a metal zone in the mid 90s. It was put in his pedalboard between his Diamonds and Pearls Tour and Act I& II Tour (support for Love Symbol Album) around 1992 until the late 90s it was spotted on his pedalboard on July 9th 1996 while he was performing for The Today Show on NBC. There was also a close up photo taken of his pedalboard in the mid 90s which the Boss Metal Zone MT-2 pedal is clearly seen.
