Here's what EMG says about the SAX Single-Coil pickup:
The SAX Set has an unmistakable Strat sound: bright, airy, with a rich bottom end. With internal shielding and a low impedance preamp, you get a virtually noiseless pickup without sacrificing a true single coil tone. The Alnico V bar magnets allow for the output to remain balanced during big string bends that makes for a beautifully articulate tone. The X series preamp truly bridges the gap between passive and active tone and feel. The creamy mid-range warmth creates sublime blues tones that are clear, strong and expressive. Experience why players the world over rely on EMG single coil pickups in the studio and on the stage.
