This Fender American Original with higher-output dual-coil pickups.
At the dawn of the '70s, as popular music trended toward the fatter tones of humbucking pickups into overdriven amps, Fender hired legendary humbucking pickup designer Seth Lover to create a distinctly Fender-flavored take on a higher output dual-coil pickup. The resulting Wide-Range pickup used large bobbins and threaded CuNiFe rod magnets to achieve its unique and brilliant sound. The Telecaster Custom was discontinued in 1979 and real CuNiFe-magnet pickups disappeared with them.
