often you see joe satch.. steve vai or even dimebag doing this..

something like pulling the whammy bar.. or tremolo u call it..

den it creates a sound like 'eeeeeein' ..sounds realli smooth and sweet sound.. does not sound like feedback to me.. sure i think overdrive is used..

joe does it that most.. pulling the trem to the bottom of the guitar.. hmmm

any idea how to do that? :)

sorry i aint clear about that :)
