hetfield's explorer(the wood coloured) is custom made dude.

" The specialty of the Kenny Lawrence Explorer:
In difference between this Explorer-shaped guitar James' other Explorers, this one has a modified headstock. This guitar is no "stock product" - it's a special design.
Otherwise Ken Lawrence is specialized in building hand-made basses which makes a guitar built by him even more unusual."

you can get the ESP or gibson one though.
