What you guys are ignoring by the way is the fact that the white covers are plastic.. which have no effect on the sound whatsoever. Getting metal covers in white will be hard...
The black EMG-like looking covers are matte black but they are metal though.. which you can clearly see.
I'm loving the NB with black cover and black allen heads, it's a symphony of evil :twisted:
I get the fact that allen heads and slugs make a difference (even if it's just the fact that the magnet, coils and polepieces als a different distance from the strings or something).. but I wonder if there's a difference between allen heads and screws?
