It’s a newer model. I have the strings tuned to pitch and the truss trods turned to a point where the nuts are practically loose. There still seems to be very little relief. Now, I understand that some might say that Ric necks should have little to no relief for the ideal setup, but that hasn’t been my experience... especially on this one. I’m getting high-pitched sympathetic vibrations up and down the neck and open A rattle. The nut height is fine and the frets are level (had them both checked). Just wondering if any of you might conclude that this neck has a permanent backbow. I could just try higher tension strings, but I’m fond of the set I have on there.... don’t think that’s a real solution to the problem either.
