I just ordered a pickup cover that does not have the pole peice hole's, its just a solid peice of metal.

I bought them without thinking about this, but I dont think that it will affect my sound to much. I read reviews on the tony iommi pickup which has a solid metal humbucker cover on it, and people said nothing about it dulling the sound. Guess im just curious as to if anyone has any experience with this

Humbuckers often have metal cases with no pole holes. The only single coild I know off that regularly have metal covers are the neck pickups in telecasters. Doesnt affect the tone in mine, so.. yeah.

The very first humbucker didn't have the adjustable poles. It's just a little tonal feature that you can play with to your taste.
