While there is obviously a strong resemblance to the HS-3 , the vintage stagger recreates the string-balance of single-coils from the 50s, producing a unique sound in the neck and middle positions with both chords and single-note soloing. And there s no 60-cycle hum.Recommended ForNeck and middle positionsTech TalkThe HS-4 works very well with high-gain amps, but the classic setup is with an overdrive pedal and a Marshall amp. The pedal boosts sustain and distortion, and the sound cleans up dramatically when the pedal is switched off. Works well in all 3 positions for slightly warmer than usual Strat sound. The vintage 50s magnet stagger is a subtle change from the standard HS-3 . It alters the overall balance between the individual strings, resulting in a little more clarity and string definition. This is most obvious on the unwound strings, particularly higher up the neck.DiMarzio Item No. DP217, HS4Get yours today; with the security of our many decades of experience and Sam Ash Direct efficient order processing, your satisfaction is guaranteed!SpecsWiring: 4 Conductor Magnet: Alnico 5 Output mV: 93 DC Resistance: 23.5 Kohm Year of Introduction: 1995 Patent: 4442749
