I recently purchased a Squier Bronco Bass. The problem I have noticed is that when pressing hard on a on a fret, the note rings sharp. If I alternate hard pressing and light pressing, it is alsmost like I am using a whammy bar. It does not occur on all frets. Does this indicate that some of the frets are not seated correctly (I do not know the correct term as I am an amature)? Or is it a setup issue? Can this be fixed? Any helpful information will be greatly appreciated.
