well dude if ya mean a dive bomb then you have to locking tremlo, if u have this then as far as im aware you wack out a harmonic if you want it high, and abuse the whammy bar :p. ANd also it depends on your set up amd guitar pedals etc on how long the notes lingers for!!!! Hope tht helped
Why doesn't my amp go up to 11, :(
