the KH-2 is available in neck thru here too, its just that since bolt on is cheaper, and people who are foolish enough to buy a KH2 only because its hammetts
signature guitar they dont care if its bolt on neck thru, set neck or one peice, dealers here will sell the hammett either way so they might as well sell the bolt on for the same price since people who buy them dont care for the difference between neck thru or bolt on , getting the neck thru will probbaly add another $500 more for people who want it, then they could just get a
jackson custom shop with the same specs for the same money.
anyway, i think ESP is definitely the most creative and best of the high profile companies (like ibanez, fender, bc rich, jackson.........)
