Detail 01
Rail design
The rails are described as providing even balance from string to string and increased sustain.

Independent shopping perspective
Built around separate JB Rails bridge and Jazz Rails neck pickups, this black Seymour Duncan set is made for a 7-string guitar. The bridge voice brings punchy low end, defined mids, and singing highs for parts that need to remain clear in a crowded mix. At the neck, the Jazz Rails is voiced with full, even output, chimey treble, and robust bass. Its rail design is intended to keep string response balanced while adding sustain.
