    Default Covered humbuckers? Differences between open-coil?

    Ok so I'm curious? Do covered humbuckers sound a lot different than uncovered? Im trying to get the green day tone from a Schecter Zacky Vengeance Mirror I picked up from a friend, but I wanted to know if it would hit that sound even with a chrome cover on it?

    itll sound very similar.

    ive done some experimenting and i can hear a difference. basically only in the high end which is a little smoother with a good cover on. the more gain you use, the less youll notice any difference.

    a cheap cover can really make a pup sound dull

    I hope nobody minds this video coming from another manufacturer, but this isn't a sales pitch from them, but a good illustration of the question at hand .....

    Wow.... I liked the sound with the covers on better more crunch and sustained better, maybe the cover dispurse the magnetic field possibly????

    Clean I prefered the covered. It was smoother, fuller and sweeter. Dirty I liked the uncovered better. Had a raunchier tone with more high end bite.

    Oh, and I LOVE that room he's sitting in.

    To my ears putting on the cover does about the same thing as switching from 500 to 250 Kohm volume (not tone) pot, as in when considering both full open.

    That's not Tim, it's a guy called Adam Getgood, although the clip is an official BKP production.

    It depends on what the cover is made from.

    My Les Paul copy was louder after I removed the covers--I'm not sure what kind of metal they are made of.
    I later read an interview with Seth Lover where he said some metals will affect the sound--and output is one way.

    But now I have new pickups in it, and the covers don't fit Duncans--especially the P-Rail--so it's all good.

    Best of both worlds, exposed screws/slugs for crisp high end, covered sides to protect the coils!

    I have always preferred the sound of covered humbuckers. That BKP video is exactly why.

    If that is metal that isn't effective.

    The sound change (apart from mechanical effects) is from eddie currents, and those appear in conductors inside the magnetic field. They don't have to be between coils and strings to change sound.

    The above would make a real difference only if the cover material is magnetic which of course would ruin the pickup right there.

    Having said that, I have grown to have a mental model of covers that has mechanical effects closer to the top of the sound changes list.

    Years ago, I had a '67 SG Standard and experimented with the covers. The only thing I remember noticing was a slight increase in treble response. Otherwise nothing.

    I think the WD ones are nickel silver, non-ferrous, yet can help reject RF noise.

    Besides, they give the guitar a finished look without covering the slugs/screws.

    The covers shield from RF noise, any conductor does. However, it isn't needed since the humbucker coild buck the hum anyway. The only noise difference is that the shield pieces of wire connecting shielded wire to coils under tape in an open pickup pick up some RF noise.

    thanks man, I was looking for a video like that,

    I was considering covered for my high gain paf style. now I want the uncovered, has a bit more bite by a few percent that is tough to dial in and out with otherwise eq options...
