How did you test the pickup to find out that it was wired in parallel? I'm going to eventually replace the pickup and preamp but it's something I'd like to know/learn.The pickup in my bass has only two wires. I was told that my bass was produced in 2019. I was also told that it was hit or miss on basses that were shipped with pickups wired in parallel.

I was told that it was but that seems to be incorrect. I do remember the stock pickup being 2-wire.
