I have the 18x in my Explorer now. I did not try it with the 18v mod, it didn't sound like it needed it at all. The X-Series, in my opinion, blow away the standard EMGs. I have an 81x and a 60x in there right now, and I feel like I get the same general tone that I like from the EMGs, but the muddiness is gone. Notes seem to ring clearer and just sound all around better. I highly recommend giving the X-Series a shot.
