I need some help figuring out how to adjust the truss rod on my Stingray 5. When I play frets 1-4 on the A-G strings, the notes just flub out due to hitting the frets. I would assume that wheel at the base of the fretboard is the truss rod adjustment... How would I go about actually ADJUSTING it? Also, which way do I need to turn it? The relative humidity in the room where my basses were creeped up to around 75% and it really messed my 'Ray up. I've got a very bad feeling that the truss rod may be frozen on this bass. I take it that means I'd need a new neck (which I assume will be quite expensive). Please help!
