MWHShigh output single coil,this is the Ceramic

MWHS:high output single coil voiced for extra mid range great for driving effects etc...

NWHS: are available in neck, middle and bridge versions. When used as a set the pickups are calibrated with the bridge pickup slightly over would to compensate for the lesser movement of a string as it gets nearer the bridge.Less movement mean less voltage created by the pickup and a noticeable drop in volume when you switch to your bridge pickup.Quite disappointing when it is time for the "big solo".All single coil middle pickups are reverse wound / reverse polarity,so when used as a set the neck / middle, middle / bridge combination will give you a humcancelling feature when both pickups are selected.
