Again, that depends on the guitar. I had the Norton in an ash bodied strat, so going alone by wood species you would expect the combination to be rather bright. Well - no. That guitar has a dark midrange color, and any full sized humbucker I had in there (Bare Knuckle Holydiver, AT-1, Norton) seemed to accent that. I since converted the guitar to SSS, and prefer it that way.
I had the Norton then in a Telecaster Deluxe type guitar, first with a load of appr. 400k - too bright and aggressive. Lowered the load to about 330k - better, smoother but maybe a tad too smooth. It is out again and in the box at the moment. It will certainly get another chance.
So in one guitar it was too dark (with a load of 500k), and in the other too bright (even with a slightly reduced load). And I am talking about the exact same pickup here, not just the same model. So it was definitely the guitars it was in.
