Michael J. Fox had his first guitar as a Christmas present when he was 8 years old. He then taught himself to play.
He can be seen on film in the ""Light of Day" playing a stratocaster style guitar. His best known film guitar solo, Johnny B. Goode on "Back-to the future", was actually played by LA session guitarist Tim May. MJ Fox studied with guitar coach Paul Hansen to make it really look like he was playing the solo.
The solo emulates a time machine, passing though three decades of rock guitar styles in a matter of seconds. It starts out as Chuck Berry, then proceeds via Jimi Hendrix to Eddie Van Halen.
The amplifier in Doc that Michael J Fox blows up at the beginning is marked as CRM-114. This is a cryptic reference to Dr. Strangelove, in which
the B-52 crew receives its orders over a radio device called CRM-114.
