Hi all, I have a 1990 MIJ Fender Squier Silver Series Jazz Bass that I'm looking to upgrade the pickups on. I play both finger and pick style, using a sans amp deluxe as part of my pedal board array. I'm looking to get more growl in the bottom end, and more brightness in the top. Not a fan of muddy mids or wobbly bass tones. What passive options can you recommend?
