Here's my latest brainstorm. I want to find some kind of a Fender bass with a P/J pickup configuration and upgrade the pickups. Something that is passive with a big, fat, and round tone. Obviously if the pickup can supply other attributes such as punchy mids and highs, so much the better. Not to dis active pickups, I just want a good reliable bass that never needs a battery for old school R&B, motown, country. I know some of you all have used different pickups and upgrades. Any advice or suggestions?
