The 'King of Pop' died on Thursday after suffering cardiac arrest at his rented home in Los Angeles.
His death shocked the music world, as it was only recently announced that Jackon would perform a record-breaking 50 shows at London's 02 arena as part of his comeback tour.
Guitarists the world over paid tribute to a man who sold an estimated 750 million records, released 13 number 1 singles and was recognized by the Guinness Book of World Records as the most successful entertainer of all time.
Here are just a few:
Eddie Van Halen: "I had the pleasure of working with Michael on 'Beat It' back in '83 — one of my fondest memories in my career. Michael will be missed and may he rest in peace."
Brian May: "Hard to know what to say. He used to come and see us [Queen] play when we were on tour in the States, and he and Freddie became close friends... the world is a more colourful place thanks to Michael's work. RIP Michael."
Shinedown guitarist Zach Myers: "I am more saddened than I can remember in maybe the last five years. Call the guy whatever you want... judge his actions, judge his judgments, and judge the man any way in any language you want. But Michael Jackson was the best. There was no one better. There never will be anyone better."
Slash: "Really sad news about Michael. He was a talent from on high."
John Mayer: "A major strand of our cultural DNA has left us. RIP MJ."
