Psarkissian,
Update to the story. I decided to take a look around in the guitar last night. Maybe new strings, etc. Just to see if there was anything obvious. Bit of a rattle, however I know there are no ball ends. Took off the back cover plates, nothing. And yeppers millions of circuits and molex connectors, etc. Just for fun, (Yes I know my way around computers and circuits -- static grounded myself btw) pulled the pickups molex, and re-seated it. Boom all good. Pickup output back where it was.
Me think that there was a bit of oxidation on the molex pins and receivers. So back in action. Very odd, not sure why that would happen however it's something to put in you basket of tricks.
If that didn't work, then it was off to the shop.
Thank you.
