The Estuary--Help With Chord/Walkdown Riff

[SamBernstein]

Been working on The Estuary by The Railsplitters by ear and I've got most of it but I can't seem to figure out the little chord progression walk-down thing that gets repeated several times throughout the song.

The part in question is first heard about 8 secs in https://youtu.be/rhkJu9OAoxM?t=8s

Would greatly appreciate any help getting this figured out--really fun, satisfying, and pretty easy tune and this lick would add a lot.

Just listened to this nice little tune. Sounds like Bm, A, G to me. Try (G to E string) - (Bm) x457, (A) x245, (G) x023. Happy Holidays!
