Kerry King

They were used on all guitars to record Reign in Blood, both him and Jeff. Those pickups were also creme-color-only, in those days, and you can see photos of that too.

According to Kerry, he switches to this pickup for the intro to the song "Dead Skin Mask"

"He gets his aggressive crunch, overdrive and sick lead tones from the EMG 81, EMG 85 and the PA2 Gain Boost Switch that makes up his signature EMG KFK Set."

Kerry on Floyd Rose vs Kahler: "You learn on one or you learn on the other, and I learned on a Kahler."

Kerry's signature EMG pickups.

"Common features on his signature guitars include Kahler Tremolo systems (same model as Jeff), EMG pickups (typically his signature set of KFK 81/85), a PA2 gain boost circuit, and occasionally a Sustainiac – he used to use a Fernandez Sustainer but his new Dean V features a Sustainiac."
