That's an interesting idea, thank you! I'll try to check the polarity of magnets.I see the pickups are 4 wire.... I just had a guitar in the shop with a duncan lil '59 that was mis-wired at the factory. The wire codes were all jacked up, I had to figure it out with a VOM, a magnet polarity tester, and some thought process. Could be they screwed that up, or installed two magnets with the same polarity in the coils (see vintage firebird construction; the magnets go through the coils). Test magnet polarity; one should be N, one should be S. At that point if your tech can't figure it out, send back to Lollar.
