The Peavey Butcher 4x12 is a guitar cabinet that appeared as part of the stage set on the Parade tour. It was covered in a paisley print and was accompanied by a matching Peavey Butcher cabinet. A wall of these amplifiers appeared at the back of the stage.
On Prince's tours in the 1980s, the guitarists' amplifiers tended to be kept off stage, so these amplifiers were almost certainly just part of the set. There is however, some photographs of Prince using a single cabinet for onstage monitoring.
These cabinets also appear on the cover of Sign O The Times. They now reside in the Parade room at Paisley Park.
