I've been trying to get my Geddy Lee to register more low end. EQ can't do it without making it sound like mud. I love the passive natural fender sound so I dont want to throw in any pups that are going to make it sound like a puddle of mud/linkon park/incubus bass sound. Not to knock on it or anything it's just not me. What I want is a nice vintage sound with lots of low end, beauty and the beast. Any reccomendations on a pick-up upgrade?
