Supercharge your Jazzmaster® with classic Fender wide range humbuckers that will fit any Jazzmaster with no modifications needed. Everything that you love about the Wide Range humbucker but in a Jazzmaster cover. The Wide Range CuNiFe® Jazzmaster pickups deliver rich bell-like humbucking tone with full bass and clear treble. CuNiFe pickups have "hi-fi" clarity yet never lose their attack and definition no matter how hard they are pushed. Sought after by musicians of all genres for decades, the original-era real CuNiFe magnet pickups disappeared when the Telecaster Custom was discontinued in 1979.
