These Jazz Bass pickups capture the tone, feel and articulation of a great �62 Jazz Bass. We harnessed the warmth, subtle aggressive attack, mid-range growl, and the J-tone that sits just right and voiced it to go lower than before. � Why should we limit amazing tone to 4 strings? We adjusted the coil geometry and winding configuration to compensate for the different nature of extended range instruments. It�s now possible to capture the subtle characteristics of traditional �J-tone� all the way down to the low �B.� This pickup uses the wider cover size of the modern Fender Jazz V basses. � If you have an older 5-string Jazz Bass, use the 70/74 model for the proper fit. Hand built in Santa Barbara, CA, the 67/70 Jazz Bass pickups use hand ground alnico 5 rod magnets, Forbon flatwork, come with black covers, and are vacuum wax potted for squeal free performance.
