Throughout the years Jerry has Black hums and white hums, whats the difference? I always think that the Super 2 is black and the dual sound is white, but i can't figure out if I made that up or heard it somewhere around here.
no, they had super 2's in White.
No signifigance. I think it was just what was around at the time. Jerry liked to change pickups often with the thought that the magnets lost their oomph after a while.
