Thanks to all who posted, epecially to JFRICK, Andrew SA, Zreynolds, Rockon91,VHLO, Ian for your advice and examples, It really works!, I can now tap, although it requires a lot of force from your fingers to sound good and loud, and you have to hit it from an angle......Thanks alot.

By the way, Khaki King is amazing, She's like a slow version Michael Angelo, tapping on acoustic..without a lot of effort, Maybe because of the pickups....but still amazing girl not to mention beautiful face.
