I here that Hipshot Tuners balance well with the heavier Warmoth neck on a lighter body.
Any pickup that listens to the strings at two points has upper mid dips (which are at a different frequency on every string). Pickups that listen at only one point do not have those dips, so they will always have more articulation. And no, since the dips are different on every string, you can't fix them with eq.Jazz bass on steroids:
Pickup placement is similar.
Humbuckers generally have more power and sound thicker than singles.
This is the origin of the statement and it does have merit, regardless of ruffled feathers within this thread.
