well, i'll reply to yr question before it gets lonely here all by itself... false (aka artificial) harmonics are achieved by actually fretting a note and damping the string 12 frets higher. (this is as opposed to damping a string as with natural harmonics.) in classical music you fret with the left hand, damp the string 12 frets up with yr pointer finger and pluck the string with yr thumb. i've not tried it w/ a pick so i'm not sure how you'd do it if not playing fingerstyle.
Wow I actually remember "discovering" this decades ago. In a way, the false harmonic could be considered a pinch harmonic. It sounds great if you can manage it. To me it sounds like George Harrison's guitar in "Octopus' Garden".
I also gave up on this decades ago, considering it to be highly impractical - but you never know.
And nobody asked, but I am a big fan of "pinch harmonics".
When you say play with "quarter" is that some technical musical term OR do you mean an actual quarter?
Also as someone probably said in another topic in another category, humbuckers are great for pinch harmonics.
I mean .25 cents, an actual quarter. Billy Gibbons type harmonics galore. He actually uses a Mexican Peso for a pick. It takes some getting used to but it's fun.
Really hot single coils, like the Duncan SSL-6, are good too. I practice pinches on my Epi LP which has the weakest pickups of all my guitars. When I pick up my JB/Jazz loaded guitar, the harmonics are easier to do.
