Having difficulty finding just a neck #9Js Bartolini, so I'm thinking of putting a Dimarzio Ultrajazz up front of the Bart MM3 on my project bass. How would these two balance together? I hear that the Dimarzio's sound big and fat; would it add to the overall sound of my bass? Would it be better to wire this kind of setup active or passive? Thanks for any help! EDIT: Read Smash's review on the Model J. Would one of those be better and can you get them in just the neck position pickup?
