Hey getting new pickups soon and thought about covering for cosmetic reasons only...will it change the sound at all? or amount of output?

They say that metal covers 'sweeten' your tone, ie make it more round. Often this is a good thing. It's cos of how they affect the magnetic field and all that...

However, the difference isn't always too evident.
