What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.

Detail 01
The higher-output half. Pushes the front end of an amp harder for sustain and lead cut, at the cost of some cleanliness.
Detail 02
The lower-output half. Stays articulate and defined rather than woolly, so chords do not turn to mush under distortion.
Detail 03
Output levels are deliberately mismatched between positions so switching pickups does not cause a jarring volume jump.
Detail 04
Open-coil black bobbins. Matches black hardware; will look out of place against gold or cream appointments.
Detail 05
Two coils wired to cancel hum, so no 60-cycle buzz near lights and screens. Thicker midrange than a single coil.
Final check

Product questions
Straight answers to the questions shoppers most often ask about this product.
Yes, the SH-4 JB is sold on its own. The set exists because the JB and Jazz pairing balances output between positions; buying separately costs more for both.
They are standard-size humbuckers, so they fit standard humbucker routs and mounting rings. Measure your rout and string spacing at the bridge before ordering.
It breaks up earlier than a vintage-output humbucker. Rolling the guitar volume back cleans it up; the Jazz neck pickup handles clean work more naturally.
Not required. Both work with common 500k pots typical in humbucker guitars. If your guitar uses 250k pots the result will sound darker.
