Seymour Duncan, Classic Stack Plus STK-S4

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.
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.

Pickup is available for bridge, middle and neck positions.

The pickup works with all well-balanced instruments. Works equally well with maple and rosewood fingerboards.

It comes with RThree-conductor cable which 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.
