Only Fender would call a guitar with a changed radius an "Original," but points to them for broadening the playability, which to me is a higher priority. I never worry about muddly guitars iof they have decent pickups, because it's almost always a pot/cap values issue, not really a pickup issue. I think I'd go with the 1 meg pots a poster recommended, as it's easy to dial out excess high end, but if it's been damped to begin with, you can't really get it back. For me, detail is one of the fundamental virtues of most Fenders. I wouldn't bet the ranch on the CuNiFe "magic." IMO, there's no magic at all. Those pickups were disliked when they came out, and it wasn't because people are stupid or clueless. It's simply that humbuckers, including those, were not seen as bringing anything really desirable to the guitar. And nobody -- not a single human being -- was so enamored of them that they were installing them in other guitars... until much later, when the fad began.
That's a valid point - as I mentioned I have never actually played a guitar with the CuNiFe Wide Range pickups plugged in (I have picked them up in used/vintage stores back in the 1980s but never through an amp). My only point about the CuNiFe poickups is that whether or not he would find them have any kind of "magic" they would sound different enough to not be redundant with the Teles & ASAT that @JBryantfan already owns.
