All Seymour Duncan P-90 bridge pickups, including Phat Cats, are built with South Up polarity facing strings and counter-clockwise wind direction.
All Seymour Duncan neck P-90s are North Up, with clockwise wind direction, for hum-cancelling when combined with bridge pickups.
Our P-90 Stacks also follow this convention, for those who would like to split the stacks to single coil.
P-90 Silencer sets also have neck pickups with North polarity and bridge pickups with South polarity, to ensure phase consistency with other models of our P-90 line.
Seymour Duncan P-90 pickups should be in-phase with other manufacturers’ P-90 pickups.
