Hi Gary,
I've that DVD and it's a nice one.
Back then in 2004 Hanks guitars didn't have a compensated nut.
There are DIY kits to customize the nut on your guitars and also ready to fit nuts.
Well none of the hits and all of the shads recordings had the "benefit"of a compensated nut.....and they all sounded great.
So I wont bother to go that route, I'm used to the standard nut (yes I have noticed and can hear the differences) but I won't butcher my pre-cbs guitars.
Thinking of customize all my guitars .....
Cheers Rob
