I just got a Warwick Corvette Std. Fretless and after letting the neck acclimate for a few days, I decided to put alittle bit more relief in the neck. However, I noticed that when turning the truss rod, it felt really loose...too loose, like the nut was loose. So I turned it clockwise until it snugged up a bit and left it there. Should I be worried about this? I still would like a teeny bit more relief in the neck, but if I go counter clockwise the nut is going go loose again, and the neck is pretty darn straight as it is. Suggestions?
