Tab Gitar Avenged Sevenfold – A little piece of heaven live Versi 1

this is the riff that syn played (which is tremendously beautiful) during the great live on lbc for the song 'a little piece of heaven'. i just want to share this just so we could discuss and improvise for the closest tab that we could think of on the riff that we are looking for. e|------------------------------------------------------------------------| B|------------------------------------------------------------------------| G|--------9-------9---------3------3-------5--------7-------5-------7-----| D|-----7-------7---------3-------3------5--------5-------5-------5--------| A|--5-------5---------1-------1-------5-------5-------5-------5-----------| D|------------------------------------------------------------------------| so far this is all that i am able to figure out. hope you guys have a better idea of what scales that he intend to use so at least we would know the right notes that he could be using. i cant figure out how the last set of the riffs (before going back to the start) goes but the last note (on the G string) sound more like 7, 9, 10, 9 then back to start. help, in need. do give honest critics, thank you.
