I just thought from reading Damo's post that he meant the pick and flesh type of harmonic, I agree with most of what everybody had to say about them, but on a few things I must comment, 1. Bridge Intonation is not going to cause a difficulty in playing the harmonic at the 12th fret or any other fret, the 12th fret harmonic will still be 1 octave higher than the open string it is played on, string length compensation is for compensating the fretted note, 2. In standard musical notation, and most Tab any Harmonic played on an open string is usally called a natural Harmonic, pick and flesh type are usally called artifical harmonics, if we call them pinch harmonics, artifical harmonics, pick harmonics, which is the term I used for years, it really is just a matter of semantics, if anyone wants to explain some technical difference between pinch and artifical harmonics to me , I would be glad to read and learn, No I'm not mad but I have seen this before, and I'm always amused when we get to haggling over the non-specific terms used to describe techniques.................
