Victor Wooten - Double Thump Exercise Bass Tab

alright so i was looking through your tabs i realized that no
one has actually talked about the double thump technique which
he constantly uses so hear it is:

g--------------------------------------------------------------------5555-6666-7777-8888
d------------------------------------------------5555-6666-7777-8888
a---------------------------5555-66666-7777-8888-
e------5555 6666--7777-8888-------

What you do is you hit the string with your thumb going down and
then you place your thumb under the string and bring it back up
with your thumb and you pop it that way. he uses this in basically
every song i have ever seen. some times he will hit the sting well
it is open and hammer onto the fret with the finger and then pop
it with the thumb again. for example check out his classical
thump. that is what helped me learn it so check it out.
