Seymour Duncan SH-8b Invader White Pickup

The SH-8b Invader is a high-output bridge humbucker engineered for aggressive, articulate tone with serious punch. Its specially overwound coils and three large ceramic magnets deliver dense, compressed lows and cutting midrange—ideal for heavy genres where definition matters as much as raw power. This is a pickup that responds to pick attack with precision while maintaining clarity even at extreme gain levels.

Tone & Response

A 5 kHz resonant peak gives the Invader its signature presence and cut, while the EQ curve of 7/8/4 (Bass/Mid/Treble) emphasizes thick lows and punchy mids with restrained highs. The 16.8 kΩ DC resistance confirms this as a high-output design that pairs well with tight, articulate amplifier settings and responds cleanly to gain staging across all input levels.

Construction & Compatibility

Built with three large ceramic magnets and oversized metal oxide pole pieces for enhanced string-to-magnet coupling, the SH-8b fits both standard humbucker and Trembucker string spacing. The four-conductor cable enables series/parallel wiring options, and twelve black oxide cap screws ensure secure coil mounting and consistent magnetic field stability.
