Pstring, I have to disagree with you on this. Bridge Intonation has everything to do with what Damo is saying, and I’ll explain why. I’m going to talk about natural harmonics, but it is the same with all harmonics, artificial, pinch, tabbed, whatever. Your right on saying that it doesn’t make it more difficult, but if your bridge is not adjusted accurately enough, it won’t sound right. Here’s an example, play any of the 5, 7, 12 fret harmonics. Pretty easy to play, right? Yeah. But did you notice if you played all of them, which one just didn’t sound quite there like the rest of them. Well it’s the 7th fret on the B string? Why doesn’t that sound right? Here’s why. All these harmonics are all natural pitches, except that one, It’s an F# harmonic. Harmonics that play accidental notes usually don’t sound quite as bright, there a little deader that the one’s that are played of natural notes. It’s still there and you can hear it, just a tiny difference. This is where Bridge intonation comes into play, if your bridge is not adjusted right; all these notes on the frets are a little flat or a little sharp. This can cause some deadness in those harmonics. And if your bridge is way off, like it is in between notes, damo's experience is very common. To most of you it isn’t cause your bridge is probably adjusted right. I hope I explained this enough. It’s not the only solution, but I think it’s one that should be taken into consideration if deadness of your harmonics is a problem.
