Description
This 50 mm humbucker slug bobbin is designed for standard-spaced humbucker pickups and is intended for the non-adjustable (slug) coil.
The 50 mm pole spacing aligns with traditional humbucker string spacing commonly found on Tune-o-matic bridges, hardtail guitars, and modern Gibson-style instruments. Proper spacing ensures accurate string alignment, even magnetic response, and consistent output.
Molded in classic black, this bobbin is ideal for modern builds, stealth aesthetics, rewinds, and custom humbucker assemblies, while remaining fully compatible with vintage-style hardware.
