The Injector Bridge Model is one of Dimarzio's hottest hum-canceling models (185mV output) with six individual Alnico magnets. The sound is not like a vintage single-coil: highs are bright but not glassy, and lows are solid and defined. It was designed to work equally well with rapid single-note arpeggios and power chords without becoming muddy or compressed. It has about 40% less magnet-pull than standard single-coils, and this is essential for the superior speed and dynamic range with which this pickup responds to pick attack.
Paul’s setup on the guitar he played on "Fuzz Universe" was Injector Neck Model in the neck, Area 67 in the middle, and Injector Bridge Model in the bridge. The Injector is a lot louder and warmer than the Area 67 but the combination produces varied tonal colors in the 2 and 4 positions, with the Area 67™ alone providing vintage tone and the Injector™ Neck and Bridge for heavier sounds.
