Recently acquired these in a guitar I bought. I yanked them out before I actually had a chance to try them through and amp, so you'll have to ask Chris (jacksonplayer) if you want to know what they sound like. Wilkinson touts them as the closest thing to a PAF possible, Wilkinson Guitar Parts.
In terms of references I have numerous references selling guitars on HC,Sevenstring, and Metalguitarist, you can check my itrader feedback on the last two here:
