I have a question. I have a Fender Japanese Made Telecaster (about 3-4 years old) and a Fender Princeton Chorus Amp. For some reason I'm having grounding issues. I've done a couple tests and it seems like it may be the guitar. I put hands over the strings to see if it would stop the hum and it didn't work. I also checked the different pickup settings on my guitar and there's still a hum. I even had my guitar jack fixed a couple months ago. Any idea of what's wrong and what I can do to fix it? I'm recording on Sunday. Thanks!
