Seymour Duncan SH-15 "Alternative 8" humbucker pickup. Gold cover. The first production Seymour Duncan humbucker to use an Alnico 8 magnet. A combination of hot coils and the Alnico 8 magnet offer enhanced output with a huge, punchy sound full of fat mids and present upper-mids. Dynamic, doesn't get "sizzly" or dark. Ideal for heavier rock and metal styles and high gain amps. Four conductor cable for split/phase options. Includes wiring diagram and mounting hardware. Made in the USA.
