I did something that I thought would be relative simple deal. My 2006 Fender 60th Anniversary Power Jazz Bass needed a little more truss rod tightening, so I did like I've done on others. I found the appropriate washer, dropped it down the heel shaft. So far so good. The washer appeared to be very thin, but it must have been thicker than I thought. I didn't have enough threads for the nut to start. Here's where the problem begins. I've tried several ways, but nothing will dislodge that washer from the thread shaft. I'm afraid that I'm going to booger the threads on ot and then be in a real jam. Any suggestions?
