The SA is an active single coil pickup loaded with an Alnico V bar magnet that 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 magnet allows for the output to remain balanced during big string bends. The creamy mid-range warmth creates sublime blues tones that are clear, strong and expressive.
