Hi, I have a Fender Sting p'bass ('54 reissue) and need to adjust the neck truss rod (its bowing a bit) ... can't find a manual for this ... Apparently the adjustment nut is at the front of the neck (at the body side) ... sooo what I need to know is ... Which way to turn the nut to "straighten" out the neck ? And if anyone knows of a manual for this vintage of p'bass ? Thanks enormously in advance, John.
