The new CuNiFe version of Fender's Jazzmaster pickups delivers an optimal vintage sound, with piano lows, pleasant mids and sparkling highs. Developed initially by humbucker father Seth Lover for Fender Telecaster Custom, CuNiFe pickups have fallen into obscurity after being phased out in the seventies, but not into oblivion by Fender aficionados. In this new Jazzmaster set edition of Fender, the copper-nickel-iron screws deliver hi-fi clarity with pronounced Treble and a smooth sound for Fender Jazzmaster models.
