The Seymour Duncan STK-S4 has a new patent applied for design to remove hum and preserve traditional single coil tone. Recommended for country, pop, surf, rockabilly, blues, ska and classic rock. This revolutionary design injects tunable "negative hum" into the pickup circuit. Each unit is individually factory pre-tuned to offer the optimal traditional single coil sound with no hum. Available for bridge, middle and neck positions. For all well-balanced instruments. Works equally well with maple and rosewood fingerboards. Three-conductor cable allows splitting for true single coil mode. When three STK-S4s are all split, the middle pickup is RW/RP allowing hum-cancellation when used with the neck or bridge pickup. Players include Nuno Bettencourt / Dramagods.
