The Seymour Duncan SBP-4 Steve Harris Signature P-bass pickup is the Tone of the Beast that has blasted countless eardrums and inspired millions. The pickup relies on Alnico 5 rod magnets and a unique vintage-hot coil wind that delivers a forceful sound with pushed mid range and tight bass and treble response. Measuring in at 13k DC resistance, the SPB-4 is more dynamic and sensitive to Steve's unique two finger playing style and drives the preamp section of an amplifier hard without clipping.
