So, I opened up my bass and found everything soldered in but as I was looking around, the battery wire became disconnected from the jack. I soldered it back in place and now the bass doesn't work at all.....and when GC put the back cavity back on, they used 3 different type of screws.... So I will do some homework and find a decent and REAL luthier to fix my bass. I will NEVER take any of my equipment to GC ever again!!!!!!! Lesson learned!!! but I'm sad that my G&L will be out of service for a while!
If memory serves, you're working with an L2500, no? That bass would run without a battery, so if the battery wire from the jack came disconnected there would be no effect (in principle at least, if there were no other shorts). Maybe the problem is not what you think—or at least what you took to be the battery wire was not that. I assume you tried to run the bass in passive mode?
