My new MIM JB came with a stick on it saying Standard Jazz Bass, alder body, one piece maple neck,rosewood fretboard, nickel silver jumbo frets and upgraded Standard Jazz Bass pickups. Anyone knows what's new on these pickups? According to Fender's website: "The J-Bass now incorporates two Bi-Pole pickups fashioned after the American Series pickups." Please, anyone knows what about these pickups. Anyone have compared these new ones with the MIA JB pickups? Is it the same? I'll gain any benefit changing these pickps for another one like EMG, Seymours, DiMarzio, etc ... The serial number is MZ1164802. Thanks.
