So I've finally got to the point where I can create a harmonic on all the strings. My only question now is, should the harmonics sound different when holding down different frets?
For example when I do a pinch harmonic on the high E string and then when I do a pinch harmonic on the 3rd fret (G) on the same string (E) should their be a difference? I thought there should be, but I'm getting the same harmonics either way...

Advice would be nice.. Thanks
Depending on your thumb position of your picking hand( fretter of the harmonic) you can produce any note of the harmonic series. Try moving back and forth with your picking hand.
