little introduction:
Hi i'm formatoA3 from Italy my favuorites bands are death, at the gates, and Dark tranquillity im just playing the guitar from 9 months (an Ibanez rg)
ok is enought.. ah trey Azaghtoth(morbid angel ) , chuck shuldiner(rip) , joe Satriani are my favourites guitarrists.. kk

so I know how to make tap, pinched or artificial, natural harmonics
but always I see Satriani videos he crosses his arms and uses whammy bar for alter the pitch of the harmonic somebody know how can remake the same effect??

please answer to me

he does an AH on an open string then for some reason uses his left hand to do the whammy bar.

he uses the same technique an satch boogie? (I was thinking he makes an NA on the pick-up and uses the whammy)

he does a pinch harmonic on an open string which is why he uses his left hand to use the whammy, i know because i watched him do it, and in his interviews he said thats what he does.

I've seen in one of his tutorials that sometimes he does very squeeky pinch harm's by slanting the pic even downwards a lot.
