Ten years ago on this date, a red Gibson SG was sold at auction for $570,000 at auction in New York City. As you can imagine, there was a story behind the value: George Harrison had used it during the recording of The Beatles' Revolver and John Len**n later sued the guitar while recording The White Album. Remarkably, that's far from the Most that's ever been paid for a guitar at auction. In fact, Seven six-strings have brought in more.
