Seymour Duncan Nazgûl / Sentient Humbucker Set Seymour Duncan's matched set for modern metal. The Nazgûl bridge pickup is a high-output ceramic monster — huge low end, aggressive midrange grind, and screaming harmonic content that stays articulate under extreme gain, so fast riffs and low tunings stay tight instead of turning to mush. The Sentient neck pickup is its perfect counterpart: moderate output, warm and clear with a smooth, fluid voice that makes leads sing without going muddy. Together they're one of the most popular passive metal sets Seymour Duncan makes — passive output and dynamics with the tightness and aggression to hang with any active pickup. Includes bridge and neck humbuckers, 4-conductor leads for coil splitting, standard humbucker routing. Built for progressive metal, djent, and anything heavy.
