The same thing happened to me also, when I opened the box for my 2003 JS1000 the A saddle had slid all the way forward. I reset the saddle and checked the other ones. I noticed the rest of saddles were not as tight they should be. I tightened the rest of them almost a 1/4 of a turn. You should be careful not to over tighten when doing this. I have not had anymore problems out of mine except the post on the tremolo bar is to short for the new tremolos I think. When I have the high pass filter on the bar does not clear the volume knob. I raised the cavity the bar fits in 1/8 of a inch and it works fine now.
