So I'm going to measure a few of my Fender necks tonight to examine exactly what neck profile/size each guitar allegedly features. When measuring the neck, I'll be using a vernier, with the strings slackened off so I can measure the wood exactly. Question is, where exactly should I be taking the measurements from? Just before the 1st fret? Just after the 1st fret? Just before the 12th fret? Just after the 12th fret? Sounds like a simple question, but I've never done it before.
