The input jack on my bass guitar isn't in place, it slipped under the pickguard. So do I have to take the pickguard off to get at the thing and put it back in place? If so, how do I take off the pickguard?
the pick guard should loosen up with a few turn of some screws, and you should be able to fix the jack, without taking everything apart......
I'm pretty sure if you can get the jack with a pair of small needle nose pliers, you can grab it out. then just put a nut and a washer on it.
Okay, I took off the pickguard and it turns out one of the wires is snapped, I can solder it back but I don't really know much about the insides of the guitar, is there any online explanation?
