Ok, so this is standard tuning, but i might experiment with others later. anyway:
Intro
------------------ -------------------|
------------------ -------------------|
------------------ -------------------|
-2-2--5----------- 555555555555555555-|
------------------ which eventually switches to -------------------|
------------------ -------------------|
Method one
----------3-------3-------3--------------------3-------3-------3----------|
------7-------7-------7-------7------------7-------7-------7-------7------|
----7---7---7---7---7---7---7---7--------7---7---7---7---7---7---7---7----|
--------------------------------------------------------------------------|
-3------------------------------------3-----------------------------------|
--------------------------------------------------------------------------|
then, when the bass note switches:
----------3-------3-------3--------------------3-------3-------3----------|
------7-------7-------7-------7------------7-------7-------7-------7------|
----7---7---7---7---7---7---7---7--------7---7---7---7---7---7---7---7----|
--------------------------------------------------------------------------|
-7------------------------------------7-----------------------------------|
--------------------------------------------------------------------------|
make sure you let all the notes ring during these sections
and that's it. email me for help/ suggestions
