The Seymour Duncan Loomis Noumenon Signature humbucker pickup set gives you the tone that shaped Jeff Loomis' influential metal sound. These passive humbuckers deliver the dynamics and control that Loomis relied on early in his career. Built with Alnico 8 magnets, the 6-string Noumenon set provides high output and a thick low end while maintaining articulate highs. The Noumenon pickups come with triangular bottom plates for drop-in installation in standard humbucker routes.
