As a direct replacement for 5-string Fender Jazz and other J-style basses, these split-coil pickups give you noiseless Jazz Bass tone that works for all playing styles.With traditional single-coil pickups, bassists are plagued by hum when the neck and bridge pickups are at different volume levels. While other hum-canceling pickups tackle the noise, you are left with thinner lows, a harsher midrange and a lack of dynamics. The Aguilar hum-canceling pickups feature a split-coil design that allows you to get any pickup level combination without 60-cycle hum - all while retaining the natural, organic tone of your bass. Now you can experience the deep, resonant low-end of the neck pickup or solo the bridge pickup for that sought-after midrange cut without annoying hum!Wound in Aguilar's NYC factory, the HC pickups use 42 gauge Formvar wire and Alnico V magnets for the big, dynamic tone that Aguilar pickups are known for.
