He started by saying that you shouldn't always go off DC resistance for output etc, and what i was describing (music, amp, guitar etc) the cold sweat was the best. I was trying to push a C-bomb, but he said i wouldn't need it as i was saying at a jump from my 22k C-pig to the 14k CS would be massive drop in hotness. That's where the talk of DC resistance came in....
He also talked about wire gauges, and how he's perfected each pickup to sound it's best. So overwinding can sometimes make a pickup sound not as good as he intended it to.
