A stacked humbucker with a bluesy voice that cleans up nicely. The Seymour Duncan STK-S6 Custom Stack Plus Guitar Pickup features a patented Stack Plus design with a voice familiar to the SSL-5 Custom. It is recommended for blues, rock, pop, and classic rock. The STK-S6R has a revolutionary design that injects tunable negative hum into the pickup circuit. Each stacked humbucker pickup is individually factory pre-tuned to offer the optimal traditional single coil sound with no hum. Use this Seymour Duncan pickup in the bridge position with a Duncan Classic Stack Plus middle and a Duncan Vintage Hot Stack Plus neck for a punched up Strat tone, or in the neck with a Duncan Hot Stack Plus bridge for the ultimate rock Strat. This Seymour Duncan pickup is ideal for all well-balanced instruments. Works equally well for guitars with maple or rosewood fingerboards. A three-conductor cable allows splitting for true single-coil mode. When three Stack Plus guitar pickups are all split, the middle pickup is reverse wound/reverse polarity, allowing hum-cancellation when used with the neck or bridge pickup.
