    Could someone explain what "aperture" means in terms of pickups. I've seen wide and narrow apertures but don't know what this means.

    In a general sense, it refers to how wide a length of the string the pickup is "seeing". Though the width of the pickup casing can be some indication (a Musicman pickup clearly has a wider aperature than a Jazz pickup), it really depends on the magnet/coil structure within the pickup, so you can have wider and narrower aperatures that are both in the same size casing.

    you can get some steel wool "dust" over the closed pickup covers to show their magnetic structure. You'll see how far the coils are form each other, this is your aperture, just as mike explained.

    Narrow aperture gise some precise and punshy sound (that I favor) and wide aperture gives you what some may call a "fuller" sound.

    Peace, JP

    PS: EMG used to offer some special "paper" that show the internat structure of their pickups.
