Thanks for any help. After some serious thought, I'd like to finally pull the trigger on a 4 string, Fender Ultra Jazz Bass. I unfortunately don't have large hands, and 19 mm string spacing is just too much for me. What I'd like to do, is replace the bridge with a Schaller 3D-4 bass bridge, or something similar ( Hipshot type A, Kickass), to get the spacing down to 16mm or 15.5mm. The question becomes, will the narrower spacing adjustment affect the pickups output? The pictures on the Fender site have the strings running nearly perfect in between the pole pieces. Will a 3mm adjustment, +/-, cause pickup problems? The adjustments would be to the A,D,and G strings, which would put the strings still nearly over a pole piece. Is my worry justified, or will everything workout in the magnetic field? Thanks again for any help.
