Ok. Neck relief. I think a lot of people are using the term incorrectly, but I could be wrong. Happens all the time. Just ask my wife. So, what exactly does it mean? I've checked all of my owners manuals, and "relief" is never mentioned, but plenty of "neck curvature". There doesn't seem to be an industry standard definition. What is it relieving? If relief is caused by loosening the truss, that means the relief is on the truss rod, as the tension is transferred from the rod to the neck. If relief is caused by tightening the truss, that means the relief is on the neck, as the tension is transferred from the neck to the rod. My logic dictates that increasing relief means tightening the truss. Increasing the tension on the rod relieves the tension on the neck caused by the strings. After all, it is neck relief and not truss relief, right? I suppose loosening the truss can be considered neck relief to an extent, because it reduces the string tension on the neck. But, that gets thrown out the window as soon as you re-tune 2 minutes later. What say you?
