    I've heard removing the covers will make them a little brighter, I dunno.
    I don't like the coils vulnerable to damage, and prefer the way they look with covers on.

    Some people will swear that the covers change the inductance of the pickup, or something like that. :-\

    Tis True....But there is a great deal of myth and magic surrounding this Can of Worms

    There's some difference...how much depends on the covers. Even changing covers can make a difference. Most people can't hear it, but why not try it. It's a cheap experiment,

    ...and that you're not potted when you do it.

    I did an experiment regarding this with humbuckers.

    My Les paul R7 came with burstbucker 2 & 3 stock. too clean and sterile for me. I took off the covers and found them to be brighter and louder. They had a little more squeel (pinched harmonics) and pick sensitivity increased.
    I bought some 57' Classic pickups and found them to be muddier with the covers on, cleaner and louder with the covers off.

    There are 2 things that affect the pickup with the covers on or off.
    First, the second coil's pole pieces are always covered with the pickup covers installed and that affects the inductance and current flow of the covered coil when the string is vibrating above it. The degree of the cover's affect on the covered coil is governed primarily by the material the cover is made of.
    Second, what the pickup cover is made of. Is it chrome or nickle plated steel?, plated Brass or copper or is it solid nickel/silver. I have the solid German nickel/silver polished covers on my Crossroads pickups and it seems to make very little difference with them on or off so I leave them on for the look.
    The cheaper covers are made of chrome plated steel and tend to block the strings influence over the second coil the most. (steel cover with thin brass electroplate plate and nickle electroplate and chrome electroplate). The Brass and copper covers have less of an affect in blocking the string influence on the covered coil than the steel ones and the nickle/silver covers have even less affect.
    The cheapest pickups come with steel covers, then brass, copper and nickle/silver are more expensive in that order.

    If the pickup seems a bit anemic, removing the cover may get you a slightly hotter output because both of the coils and all of the pole pieces are exposed with no metallic barrier between the pickup and the string.

    You can adjust pickup height and adjust the pole piece height as well to customize the pickup's reaction to string vibration. Highly recommended before unsoldering the pickup covers........ ;)

    You're all full of $hit. Potting is a verb, referring to the act of putting weed in the cover and pressing on tightly, as to have a surprise next time you got to put more pot in. ;)



    Thems jes jokes now.

    I doubt the cover would change the inductance of a pup as that is determined by the coil. I get what you mean though. the covers would absorb some of the magnetic field (being magnetically conductive and all) therefore the electromagnetically Induced emf, caused by a variation in the flux of the magnet's field would be slightly less with covers, however I think it will very very little less (about 0,5%) what you could do is let a single note ring, record it and stick it through a Fourier Transform to see the different overtones in the compound sinusoid that is the signal from the pups. then remove/add covers accordingly and let the same note ring (make sure the same pups, controlsettings and the same string (so not from a new set!) record and do a Fourier Transform on that one too, if there is difference in intensity of overtones, you've proven yer theory. should anyone plan on doing this make sure to plot the Intensity of your overtones/harmonics on a Logarithmic scale because it will be more accurate in showing all the overtones rather than just the huge peaks of the 1st 2nd 3rd Harmonics.
