Just cause you've moved your location doesn't mean that it isn't still screwed in clockwise.

This conversations gonna go on forever isn't it :rolleyes:

I understand what Hammurabi's trying to say...

e.g. if you look at a clock from behind (let's assume that it's a transparent clock) the hands aren't moving clockwise, but counterclockwise, since you're looking at it from behind. Similarly, if you're looking at the truss rod "socket" (or whatever that adjustment hole that you put the allen key into is called), if your perspective is from the headstock and you're looking down towards the body, and you turn the allen key one turn clockwise, but your friend is looking from the body up towards the headstock, it'll appear to be a counterclockwise turn for him.
