this is in standard tuning as far as i know and there is a CAPO on the 2nd fret



this is how i play this song, this is one way to pick it. you can loop this with a loop 
station and loop the below pattern and it sounds awesome
E----------------------5---------------------------4--------------------------4-------------------|
B-----7---------------------------------7-------------------7-------------------------7-----------|
G-------------6------------------6-----------------------------------6----------------------6-----|
D-----7-----------7---------7---------------7-----------7-----------------7-------7-------------7-|
A-0-------0------------0------------0--------------0------------(0)-----------0----------(0)------|
E-------------------------------------------------------------------------------------------------|

E-5-------------------------5----------------5-----4---------------------------4------------------|
B---------------7----------------------7--------------------7-------------------------7-----------|
G---------6-----------6-----------6----------------------------------6----------------------6-----|
D-----7-----------7-----------7-----------7-------------7-----------------7--------7-------------7|
A-0-----------0-----------0----------0-------------0------------(0)------------0---------(0)------|
E-------------------------------------------------------------------------------------------------|
