[quote=”guitarguy”]on my guitar i have some open coil humbuckers and i have an extra set of humbuckers with the covers on them. i am thinking about swaping them so what i did, i put the closed ones over top of them ones already on just holding them to see how it would look and they atractred. i dont think they touched. could it of damaged the magnets or anything else. also if they did touch could they have got damaged??[/quote]A cover cant damage the p/u…even if it is metallic of some kind unless it stayed in contact with the mags a long period of time but even then it might just demag it a bit

Some people do say that the covers have an effect on the tone, i cant hear the difference, and i cant see how it would make a difference, having the pickups too close to the strings can also affect intonation too, worth considering.

I’m a bass player, but I assume the same goes for the guitar pups. The covers should be non-paramagnetic and have no effect (I’d have thought).

Tone effects? I’d have thought none, but you know people with “the ear” – who swear that changing the knobs from plastic to rosewood has improved the sound dramatically 😉

No, the covers won’t reduce your volume, distance will. If you screw the pups further down to allow for clearance, then the output will be reduced. What’s called the inverse square law comes in. If the distance from the strings to the polepieces is doubled, the output is quartered.

no and no

they’re just magnets

if you leave them touching for a couple of YEARS (like 10) it might wreck them
