I could use the benefit of your collective experiences again, please! I've just re-strung my Precision for the very first time. La Bella 760 FM (previous set was the FS done in the store). I (think) I understand the whole intonation thing, but there's something I don't quite understand here. Open strings are in tune; 12th fret harmonic is great, but if the fretted 12th fret registers as completely in tune, then all my notes lower down the neck are a tiny bit flat. So, I've now got all or most of my notes from the headstock to, say, the 10th fret or so to play in tune, (except a weird 'D' on my 'G' string) but in order to achieve this, my fretted 12th fret octave notes are all showing as slightly sharp on the boss needle tuner. Could anyone shed a bit of light on what's going on here, please? I'm a beginner, so I may well be doing something wrong or missing something obvious. Many thanks.
