Arguably Tom Morello's most famous guitar, the "Arm The Homeless" custom electric guitar, which he used extensively with Rage Against The Machine. In a MusicRadar interview, he talks about the origins of this guitar.
He got it in 1986, from a place in Hollywood that builds guitars. After getting the first version of it, Morello was extremely displeased with the way it looked, felt, and played. Over the next two years, he ended up switching out almost all of its parts, save for the wood used for the body.
After trying dozes of necks, pickups, and whammy bars, he settled for a graphite knock-off Kramer neck (which he found at Nadine's Music store), EMG pickups, and an Ibanez Edge whammy bar.
