First thing I'd like to say is... HELP!
I sent my 76 Fender Jazz to a local repair man after trying to adjust the neck to have less relief. I noticed the truss rod was already tight, so I decided its best not to force anything. I didn't even try to force the headstock down or anything to adjust the neck. Next thing I know, I recieve a call from the guy saying that the thread broke. So now, if the bass is tuned to pitch, the relief would be HUGE. The neck is one with a maple board.
My plea for help really starts here. Does anybody have any advice for me as to what I could do? This bass IS my wife. I'd do almost anything to restore her.
