The sticker James Hetfield originally made said “EET FUK SLEEP” in reference to his three favourite activities (playing guitar presumably being fourth), but had to be cut down to fit on the body. ESP built it for James in 1987, replacing his Gibsons, and it was his main guitar through the Black Album period. Pivotally, it marked James’s switch to active EMG pickups, which, largely thanks to his and Kirk’s endorsement, became the industry standard for extreme metal.
