I just got one of the ESP LTD H3 1000FR's with this in it. I've only had it a couple of day now, but my initial reaction is the new Custom 14 pickup is really bright and seems to have very little low end/bass to it (but it can still do chugs-just missing a little "thump" to it), and the mids sound quite scooped. Definitely an aggressive attack from it, and cuts through the mix quite well. Will need to play it a bit more to form a final opinion.
