Right now I have Fender CS '60s pickups in my Fender Classic '60s Jazz Bass. I am very pleased with the tone, very warm and growly. However, the bass has a 7.25" fingerboard radius so the A and D strings are weaker in output. The poles on the CS '60s are all raised, but not staggered. In fact, the poles on the E string are raised the farthest. I think that pickups with staggered pole pieces, meaning flush on E and G but raised on A and D, would compensate for the round radius and provide me with better string-to-string balance. I seached around a bit, and I found that the Lollars and Lindy Fralins are the only makers that offer staggered pole pieces in their Jazz pickups. For my tonal preference, the Lindy Fralins seem a little too bright and high-mid present, but the Lollars seem to fit my tonal preference exactly. I found this post: http://www.talkbass.com/forum/showpost.php?p=6818745&postcount=2 This post almost sold me on the pickups, but I would like to hear more opinions.
