Js1000 nut problems
I'm having problems with the nut on my Js1000. It has a shim underneath and i notice that when i pull back on the whammy bar, the tuning goes sharp, and when i depress, it goes flat. I am noticing that the nut is rocking back and forth as i pull up and/or depress the bar. I took the the nut off several times to make sure the nut was butt up againts the fret board and flat on the floor of the cavity, but for some reason when i screw the nut in place.....i always seem to see a hair of space between the nut wall and the edge of fretboard.......i even tried to put a thin shim to stop it from rocking toward the edge of the fretboard, but that didn't help. It still rocked both ways.......just enough to bring the strings out of tune.
I'm suspecting that the shim or the floor of the nut cavity is not level causing the edge of the nut to not fit flush with the edge of the fretboard......
Any advice on how to go about fixing this??
