Hi! im seting up my new 78`jazz, and the relif was to tight. I turn 1/4 the rod counter clock wise (its in the headstock) and 4 hours later it did nothing. I just turned a little more and it became loose, like it was not adjusting nothing any more.... maybe i have to turn it clock wise.... I freted the 1st and last fret and checked the high of the string in the 12th fret, and was to low.
