How high is your bass?

[Richard Prowse]

I'm not talking about substance abuse here. I was watching a video where a guy said that, when standing, the 'nut' (where the strings meet wood at the scroll end) on your bass should be roughly the same height as the space between your eyebrow and hair line. I play with my bass higher than this and have been experimenting with it lower. When a bit lower, the bass balances more easily, but I keep going back to having it higher. Does anyone have one of those golden rules regarding bass height? Gary Karr's bass always seems very high.
