So I wired up the pickups and they sound great, but only indivdually. When they're both full on, or in series mode (I have a series/parallel switch installed too), they sound less ballsy, thiner, and with less volum comparing to the output when either pickup is soloed. Sounds like a case of phase cacellation. Does it happen because it has something to do with having two side by side coil in each pickup? Does it happen with your pickups too?
