I managed to find a 2013 LP-100 that matched the specs of my 2014 model. I have set it up,adjusted the releif,intonation etc... I am now playing ping pong from one end to tne other fighting string tattle. I had a rattle on the first 3 frets. Adjusted the releif etc and it was awesome....but the rattle moved to the 12th fret onwards...I cant seem to find the hapoy medium as when I do the action is way to high at the 12th fret. Now my thought is this ( experts dont laugh....) It didnt do this when I got it. It had 9s or 10s on it. I put 8's on it to match my other LP. I think the nut is cut too deep and designed for the heavier gauge strings. Thoughts?
