im looking for a neck position j pickup for my peavey millennium that has a lot of growl and low end. right now im looking into the Seymour Duncan Vintage Jazz Bass® Pickup and the Fender® Accs. Custom Shop 60s J-Bass® Lead Pickup. i have no clue how either of these sound. if you have any input or a suggestion of any other pickup, it would be much apprecciated.
