Hi, What would be the best Passive Pickups to fit with My J-Retro Deluxe unit on my Fender Geddy Bass? They would have to be Humcancelling. I'm looking for the Marcus Miller slap sound, but at the same time have the ability to switch to a nice fat bottom heavy sound. What pickups does Mr Miller use on his famous Fender bass? There really are so many Pickups out there to choose from.
