Simply put, pickups are the heart and soul of an electric instrument’s voice. V-Mod pickups—crafted with a proprietary blend of alnico magnet types. V-Mod Jazz Bass pickups are modified versions of our classic vintage pickup designs. These single-coil pickups use alnico 5 magnets on the treble side and alnico 2 on the bass side to deliver classic tone with all the vintage warmth and crisp, clear sound that made Fender a legend.
