Hi all- Please excuse if this is a tired old question, but the search results under "jazz" are almost unfathomable! I need to know if the pickups provided by the factory on the Fender Standard Jazz bass (MIM) are significantly different from those on the Squier Affinity Jazz bass. Would I hear a noticeable improvement by installing the MIM Jazz pickups in my Affinity Jazz? I have no intention of going to an active preamp, I'd like to keep it simple and just get a better sound using the passive setup. TIA for any info.
