This might be a silly question and I'm finding it hard to put into the proper words, but why do some basses appear to have their strings running diagonally up and down a neck or closer to one side of the neck? Or maybe this is a better way to describe what I'm seeing - I've seen some basses where say the G string has barely any space between it and the edge of the neck on the first fret, but as you go down the neck to the 12th fret, there seems to be more space, and all the other strings do that in parallel. This would mean the E string looks like it's almost hanging off of the near side of the neck once you reach the 12th fret or whatever. Is this a serious issue with the neck or maybe the bridge? Can this be fixed? Does this affect play-ability? I saw a couple instruments I am interested in purchasing where the strings look closer to one side of the neck than the other on the lower frets and then the space grows as you go to higher frets.
