Thanks for this valuable post. I also changed the original string set for NYXL 9-42, I really like their rendering. Just after this the guitar acquired a new dimension. I was anxious about a bad wiring, it was simply bad strings and some work to do on the guitar. So doing this I also fixed the neck, there was a quantity of sawdust there, just as in the pickups and electronics compartments that I have opened to check the wiring. People did a good job building this guitar but had no time left to clean the dust... My amp is a H&K GM40 very light for a tube powered amp, adapted to my music tastes. I agree moving PRS pickups can totally change the sound. I will test your pickup config. Thanks.
