Description
This 52 mm humbucker slug bobbin is designed for F-spaced / wide-spaced humbucker pickups and is intended for the non-adjustable (slug) coil.
The 52 mm pole spacing aligns with wider string spacing commonly found on tremolo-equipped guitars, modern bridges, and wide-spaced bridge positions. Using the correct spacing ensures accurate string alignment, even magnetic response, and consistent output across the pickup.
Molded in classic black, this bobbin is ideal for modern builds, stealth aesthetics, rewinds, and custom humbucker assemblies where a darker visual profile is preferred.
