I bought a loaded P-bass body off ebay to use with my Jazz neck. Well, I got the body today, put on the neck and some strings, plugged in my tuner, and....nothing. So I plugged it into my amp....still nothing. Cable and amp work with my other bass. So I took the pickguard off and checked all the solder joints, and everything looks OK. So I put my multimeter on the jacks and pots, and I'm not getting a reading. The ground wire seems OK too. Any idea what's going on. I'm an electronics noob, and have never done any of this before. Yes, I did send the ebay seller a message.
