Hey guys! I have Dimebag's book Riffer Madness and in the whammy bar part, he says he does the harmonic by just tapping it. I've been trying this but I can't seem to get a good squeal from tapping the harmonic unlike in picking it where at least I can make it wail a little. How the hell do you really do his whammy bar tricks (specifically the one in cemetary gates)?
Also how do you practice licks with weird beat subdivisions?
