So I pull my Fullerton (the off brand not a real one) out of its case and went to make sure it was in tune as we downtuned it for practice. Long story short I hooked it to the tuner and nothing registered. Thought that my tuner batteries were dead so I replaced them and still nothing. Grabbed my amp cable and plugged her in to the amp, hit the E string, not a darn thing. Fiddled with the knobs a bit and still nothing. Replaced the 9 volt battery with a fresh from the store 9 volt and still nothing. So now I'm left with no clue on what to do. I bought this bass from Ebay and she has done wonderfully till now. So I guess I'm left with pulling off the back cover and checking out solder points and what not. Since I've never done this before I'm glad I get the chance to open her up and take a peek inside but I'm not exactly sure what to look for. Just to give some quick information I have a pre-amp volume control, 2 pickups and a tone control. So is there some quick things to check inside the electrics to see where a problem may have occured? Anything I should be mindful of? I do understand basic wiring and I can re-solder things no problem so I'm not to worried but I want to have an idea on what I could be in for.
