I've swapped my BKPs around a few guitars now and found that they are very transparent to woods. So, Muttley, I think your experience is coloured by how the woods of the guitars is colouring the sound.
Ive asked Tim to give the pickups numbers for EQ off the top of his head (so this shouldnt be taken as gospel: I put him on the spot for it and he was helpfull enough to answer):
Me: If a warpig is bass, mid, treble, 5, 5, 5 then what are the miracle man and nailbomb
Tim: Hmmmm....miracle man is something like 6, 4, 7 and nailbomb is about 5, 6, 4.
As to the question: I can t answer, I've never played a nailbomb.
