Hi all. I am new user to this forum. I have an original 1976 Telecaster that I have never modified - wiring, pickups, etc. About a month ago, I noticed that the neck pickup sounded a bit weaker/thin than usual. Last week I noticed that if I roll the tone knob all the way down, the neck pickup loses all volume. If I turn it back up, the neck pickup returns. This behavior is not exhibited on the bridge pickup. :-\ I removed the control plate and looked at the electronics. Visually, all the connections are still intact. I'm not even sure where to start with a diagnosis as to what would make this happen. Can anyone point me in the right direction? Thanks.
