Hi, looking for little guidance really. I have just bought a Yamaha RBX270 bass. My action is too high, and I've been looking at stuff around the web to help me set it lower. I'm a little confused re the neck relief. A basic question I need to ask is this: - Is the neck supposed to be perfectly straight in accordance with the body? I've done a crude diagram to explain my question. 'A' is a slightly exagrerrated (to show the point) view of the side of my bass. My neck is not straight to the body, subsequently the string (red) is at different heights around the fret. Should I really be looking to set the neck perfectly straight as in 'B'? Once I understand how the neck should sit, I can begin my other adjustments.
