the only problem I see with this is that you really need the 3rd to
establish the harmony as F7.
I myself don't find it useful because it contains two 5ths...pretty
redundant and thick sounding, and without the 3rd there isn't to
much movement in the voices.
I would suggest this, which is just as easy to grab and fully
establishes the dom7 sound:
Also, for the other poster, yes, if you add the G note on the high
E string it would be an F9 IF the 3rd was present. Other wise,
yes, it would be a sus2 or perhaps and add2, IMO:
I think I would like to call it F7sus2? In any event, it's a cool
voicing....I like it, especially when you drop the 5th (the C note
on the A string) which makes it sound a little to thick in my
opinion (ooh....might sound cool with distortion though!).
