Marty Friedman's 1985 Jackson Kelly San Dimas, which was used on Megadeth's iconic Rust in Peace (1990) and Countdown to Extinction (1992) albums, is currently up for sale. It's also reportedly one of the first 500 guitars Jackson ever built, which probably explains why it could eventually sell for as much as $125,000.
In addition to the two mammoth Megadeth albums, the storied guitar was also Friedman's axe-of-choice for Cacophony's Speed Metal Symphony (1987) and Go Off! (1988), as well as his solo albums Dragon's Kiss (1988) and Scenes (1992).
