I have an Atelier Z 5 string bass that currently has the 4.5" wide NJ5FS pickups in it. The bass has the sadowsky preamp in it and I'm into the Marcus Miller, John Pena,Alex Al sound. I recently installed a set of DiMarzio Ultras in my 74 Jazz Bass which also has the Sadowsky preamp in it and compared the two basses side by side. The Jazz sounds a lot clearer, louder and zingier than the Atelier Z. So now I'm wondering if I have the best possible pickups in the Z.I wish DiMarzio made a 4.5" wide Ultra Jazz pickup. I do have a set of Ultras for a 5 string and I was thinking I could place them into the nordstrand pickup covers, but the holes for the pole pieces don't line up.So that wouldn't work. Now I'm looking for a hum cancelling pickup that is similar in tone characteristics and output to the Ultras. Is there such a thing?
