Check the listing for details. Seymour Duncan SH-8b Invader Humbucker Pickup - Black Bridge. Color: Black, Condition: New. Listed at 109.00 USD. Built for the Heaviest of Heavy Tones No matter how meek your guitar sounds with its stock pickups, the Seymour Duncan Invader humbucker will transform it into a high-octane riff machine. This high-output humbucker contains a mixture of hot overwound coils and girthy ceramic magnets, churning out scorching tones with plenty of depth and articulation. Meanwhile, oversized metal-oxide pole pieces produce an expansive magnetic field and an extra-wide frequency range, giving rise to massively thick sounds with a near-subsonic low-end response — especially in down-tuned scenarios. That said, Sweetwater guitarists also hold high regard for the crunchy treble of this pickup, which ensures a well-defined sound, no matter how deep you dare to plunge.
