Hi! I live in Brazil and I need information to check the truss rod setting for my Ernie Ball Music Man Stingray 4 strings. I don't have a owners manual, but in some basses magazines indicates the string clearence - capo at the first fret and last fret depress - between the bottom of the 4th string and the top of the 8th fret should be approximately .015". This is correct? Please, also I need information about string height factory recommended.
