It sounds fairly straight to me, he may have a touch of chorus on there but very subtle.
John gets a lot of his sound out of his 12 string acoustic but it really is only 11 strings(he takes the high G string off) he says he prefers it this way. Also he is in an alternative tuning. I can't remember the individual strings but it is in a 'C' tuning of some sort. I remember seeing a you tube video a while back where he explains this. Plus he has a capo on the fourth fret which would make the song in the key of "E".
And he is a big fan of the beat box.
A great song, thanks for sharing I have never heard this one before.
