Prince used a number of amplifier set ups over the course of his career. His first amplifier was a Mesa/Boogie Mark II. He first used this amp on the Prince tour in 1979 and it remained his main amplifier until the late 1980s. He initially paired this amplifier with a Marshall 4x12" cabinet. Around 1999 he switched to Bag End D-12M cabinets and continued using these live and in the studio until the early 1990s. Prince switched from Mark II to Mesa/Boogie Mark III amplifier heads in the late 1980s.
