I know many out there have upgraded the stock PU to a SD rail type one. I've already installed one on mine but seem to get unwanted noise. I have what I can only describe as scratchy pots as well so I'm looking to totally redo the wiring and do some serious shielding. I'm going to finally get me a soldering tool and try it out. I'm looking for examples of what has been known to work really well based on your guy's experience with this particular PU.
