No probs......had my EX-1 out of the case earlier today playing it up against the Tele I am trying to intonate and really love all the combinations as when in the middle PUP selector position you get the usually 2 humbucker together sound, then when splitting the neck and keeping bridge humbucker gives a nice out of phase sound, then did the opposite and split the bridge and dropped neck back to humbucker and it was slightly brighter, and finally split both which did not sound quite as good as the other 2 combinations which you only get from being able to individually split each PUP independent of each other. With all the dramas I am having with the Tele it really only has one sound that I cannot replicate on the Explorer, that being the really bright bridge PUP sound that is so distinctive and gives that chicken pickin country twang. Mind you split bridge PUP sounds more Strat than Tele which is still cool.
I reckon the wiring was not too hard and probably less fiddly than trying to hook them all up together on the one without making a right proper mess of things.
Your axe and your time but for a handful of bucks and maybe 15 extra minutes effort it gives you a few more really nice and useful tonal options.
