Hollywood Undead - Street Dreams Chords & Tabs

This is one of my first tabs and I kinda of was doing random things on my guitar when i 
heard a familiar sound. Later I realized it's the intro to one of my favorite songs!
[ Tab from: https://www.guitartabs.cc/tabs/h/hollywood_undead/street_dreams_tab_ver_2.html ]
So here it is:
-Standard tuning
-in the song I don't know what instrument does this sound but feel free to pm me 
dudes2009@live.ca for any corrections.
