I think that's the right word anyway...
pretty much my guitar is always slightly out of tune when it's in tune.
because when i changed string gauges i played around with everything and ****ed it right up.

Its out of tune when you're playing open chords?? That sounds like your guitar simply isn't in tune.

You only need to fix the intonation if your 12th fret is out of tune with the open string.
