The Strat is now complete, unstaggered poles. The centre pickup was not reverse wound, so I swapped the magnet direction. I had to dribble in wax and glue a plastic card base plate on to keep the poles in place. It sounds amazing.
I popped open a Squier 2005 PJ, but the pickups had already been replaced with a design I dud not understand. I will look at another bass to test.
