Regarding this discussion....... Our default 4 string spacing is 20mm, so the string alignment will not be perfect. Please remember that all of these pickups are designed for the more normal 4 string spacing which is 19mm (¾") at the bridge. Our 5 string spacing is on the wide side as well, at 19mm. Also, we do not do even string to string spacing at the nut. Our nut is cut so the "spaces" between the strings will be the same, not the distance from center to center on the strings themselves. We allow a little more clearance on the G string from the edge of the fingerboard, to prevent slipping off the edge from bends and pull offs. We also push the limits on our humcancelling 5 string J pickups in terms of how wide we can get the pole pieces to the end of the pickup cover. So factor all of this together and perfect visual alignment with the pole pieces and fingerboard dots become impossible. However, as has been addressed earlier, none of this has any effect on the response of the strings to the pickups.
I could switch to solid covers, but then it becomes difficult to radius the pole pieces as we do for more even tonal response.
