Passive single coil pickup. This single coil rails sized humbucker delivers high output, loads of midrange harmonics, and an aggressive crunch that make this a great bridge pickup for rock and metal. Chords are full and powerful, and single notes jump out with amazing sizzle. A Hot Rails in the bridge position will literally transform your Strat into a completely different instrument. This pickup is a drop-in for any standard single coil pickup route. - Number of Conductors: 4 - Dc resistance: 16,6 kOhm - Colour: White.
