Ceramic Humbucker, Optimized for Doom The Seymour Duncan Slug humbucker pickup lets guitarists craft better heavy metal doom and sludge tones with less effort than ever before. Each Slug humbucking pickup features two ceramic magnets that churn out massive volume and presence while preserving the natural warmth and response of passive pickups favored by vintage forerunners of doom in decades past. GearNuts guitarists find the supercharged bass presence and low-mid definition of Slug pickups make sultry riffs and down-tuned guitars more gripping and visceral for players and audiences, too! Note: Slug pickups are slightly longer than a standard humbucker. Custom mounting rings are included to accommodate a bobbin length of 2.87 inches. Mounting a Slug pickup in a pickguard may require slight modifications.
