This is probably an obvious question to most of you, but here goes. I just installed a pair of DiMarzio DP 123's in my Lakland JO (with concentric pots). I followed DiMarzio's instruction to the letter, but I am not sure whether I have them wired in series or parallel. I connected pickup 1's white and black wires together, and pickup 2's white and black wires together. In other words, pickup 1's white to pickup 1's black and pickup 2's white to pickup 2's black. This was my understanding of DiMarzio's instructions, which simply say "solder the black wire and white wire together." However, when both pickups are on full the sound is a bit thin, then kicks in noticeably if I cut back the bridge pickup to about 80%. When each pickup is soloed this does not happen. Is this just normal phase cancellation, or have I inadvertently wired these pickups in parallel? Thanks in advance for any input from wiser heads!
