I love finding weird chords...

Do we know what the bass is doing at this point? It might be the missing piece of the puzzle.

Bass is silent and the strings are holding a C pedal tone. I think I may have the sound, too; I used an electric 12 on the neck pickup, coil split and hit the 4 high courses quite hard and quickly while muting the low courses. Sounds pretty damn close!

What I find interesting is that the chord will change names when you change the spelling or take the inversions up the fretboard.. and the scale will change which allows a different note selection when soloing.
So, that F6sus4 with a F in the root note position changes when you make the G the root note and becomes G7... and when you make the D the root, you get (almost) Dm11...

.. great fun!
