Strings between pole pieces?

    I have an SX fretless bass. The spacing at the bridge is wide enough that I'll add another string (c string) using a 5 string Kahler fixed bridge.

    The outer spacing of the new 5 string (e-c) will be the same as the old 4 string (e-g) spacing. This means that the strings will no longer fall between the pole pieces of those SX pups (surprisingly good). Is that going to be a problem.?

    I do have a set of MIM blade ceramic pups (that I took off my Squier DJAV) that I can put on the SX. Am I going to have to use them? Anybody out there who doesn't think the position of the string, relative to the pole pieces is crucial?

    There's one way to find out, but I would guess that the individual string volume is going to be all over the place without the blades.

    So, you're going change a 4-string into a 5-string, but not change the PUs? Not a good idea.

    I don't think it's that crucial, but it depends on the pickup. This works just fine:

    And there's this guy around here who does 4-to-5 conversions all the time, often reusing the original Fender-style pickups....

    Yes I can use those spare MIM blades, but those cheap SX ceramic pickups actually seem less brittle & have more punch than the blades.

    Just do it, it makes no audible difference.

    The Bill Lawrence P-46 (P-bass) pickup pair has five pole pieces per unit. Only half of them line up with strings perfectly.
    Works just fine. Even volume everywhere.

    I think you'll be fine if your pickups have all the same magnetic polarity across the strings, like a standard single coil jazz, or a mm humbucker. IOW, where the coils span all four strings.

    If you try this with a P pickup, where two strings have one coil with north magnets, and the other two have another coil with south magnets, there's a very good chance you'll hear a big difference in tone and output from that middle string. It's not just the location of the pole pieces in relation to the string centres, but also the magnetic field that's created by this side-by-side humbucker arrangement. There are many humbucking J pickups with side-by-side coils like this as well.

    Other than the polepieces sticking up too far, those SX pickups are probably the best thing about those basses.

    They are shockingly good-robust like alnicos. The wood work is impressive too. New nut, new bridge, new pots (later when they distort) & I got me a good instrument.

    I'd throw a good switchcraft Jack in it as well....
