RWRP

Abbreviation for “reverse-wound, reverse-polarity.” This refers to a single-coil pickup with its magnetic pole reversed and wire wound in the opposite direction compared to the other single-coil pickups in the same guitar. When the reverse-wound/reverse-polarity pickup is selected in combination with a standard-wound and polarity pickup, a hum-canceling effect is created reducing or eliminating noise and hum in the output of the guitar.
