no no the old metallica songs never use drop D (dunno about st anger, maybe they do, but im not a big fan of that album)
original fade to black is standard E and the live version is standard D# at most.
fade to black intro solo is kinda overdrive i think, on the neck pickup, the emg 81
81 in the neck too bright in the neck IMO. Its a great bridge pickup, with lots of crunch on distortion, but way too bright in the neck. If you like a bassy neck pickup, go for 85 and if you like a bluesy kinda sound go for a 60 (which i prefer). And then there's an 89 which you can coil tap, but i dunno much about it.
