My brother plays guitar and can tap pretty good, he tried to teach me how to do it like he does but I just cant get it to ring out very loud. I will tap at the twelth fret and release really fast but all it does is a little "dee doo" that you have to really listen to hear. The pull off following the tap I can hear more, but I just can't seem to get it. Is there a secret to tapping on a bass? where can I find some instructions on it? Also, just out of curiosity, how does cliff burton tap those artificial harmonics on anasthesia? Thanks a lot!
