Hey man, I live in Hatyai, south of Thailand. Where are you???
Superhuman....
I know what you talking about, I use that technique too but I use my right index finger rather than the pick to get that super fast ham-pull off...
But no, it isn't this technique I used in my song you heard.
The buzz 'technique' is done by rolling the pick of the fret which actually acts as a 'Tap' and a 'Picking' sound... There was no hammer on pull off at all.... you get me???
