Seymour Duncan SH-4 JB Model Reverse Zebra Pickup

Seymour Duncan SH-4 JB Model Reverse Zebra Pickup

The SH-4 JB in Reverse Zebra configuration delivers the aggressive, articulate bite that made this pickup a staple in bridge positions across genres. The reverse coil winding combines clarity and punch with enough output to push an amp into responsive saturation without sacrificing note definition.

Tonal Character & Output

This pickup punches hard with a 16.4k DC resistance that generates substantial signal and sustain. The 5.5 kHz resonant peak emphasizes upper-midrange aggression, while the 5/6/8 bass/mid/treble EQ curve skews bright and articulate—ideal for cutting through dense mixes and delivering snap on fast passages.

Construction & Winding

Built on an Alnico 5 bar magnet with nickel silver bottom plate for stability and tonal refinement, the Reverse Zebra coils provide the characteristic harmonic balance this model is known for. Vacuum wax potting eliminates microphonic feedback and ensures long-term reliability on the road and in the studio.
