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