Hello there, knowledgeable people of the Les Paul forums, I am well aware that many people may have faced the same problem, and some have probably already asked for advice on these forums, but after searching, I haven't been able to find a solution for my specific situation. I am the lucky owner of this beautiful handmade Bacchus BLP '57 from Japan, a truly outstanding instrument which remains one of the best deals of my short life. The previous owner had replaced the stock japanese pickups for a set of custom handwound Alnico V humbuckers which at the time were made by a guy here in the suburbs of Paris. However, I didn't really like the lack of mids on the bridge pickup, so last week, I swapped it for a new Seymour Duncan Alnico II pro, which by the way suits me way better than the previous one. Here comes our problem : as both bridge and neck pickups work perfectly fine on their own, they are completely out of phase on the middle position. I have seen on various forums that this could be fixed on multiple-conductor wires, but both of my pickups are single conductor : I was told by the guy who swapped the pickups that the only solution was to change the neck pickup too, which I guess isn't true. Should I manually rotate the magnet on my neck pickup to get both of them back in phase? Would this affect the tone of the individual pickups in any way ? I thank you for your patience of educating an ignorant young man, grateful for the help of oyur years of experience.
