Hello. I'm new here. This is my first post. I bought this guitar below...it's a SG400 made in Korea (from the serial number). I swapped the pickups for a dimarzio paf pro in the neck and 59 in the bridge. But i'm having a lot of issues. The Seymour website wiring...the pickup is conected with the far right lug...if i do this...there's no sound...i must connect on the middle lug. The Bridge tone pickup also stopped working. *When i got the guitar....all eletronics were working fine.
