The Seymour Duncan STK-S9b Hot Stack Plus Strat Pickup uses Seymour Duncan's patented Stack Plus design with higher output than the Classic Stack Plus. Recommended for country, pop, blues, classic rock and heavy rock. This revolutionary patented design injects tunable "negative hum" into the pickup circuit designed for increased output. Each pickup is factory pre-tuned to cancel the most hum possible.
The Seymour Duncan STK-S9b is recommended for bridge position. Use an STK-S9b Hot Stack Plus in the bridge position with the Classic version in the neck and middle for a versatile, hum-free setup.
