are C/G and CaddG the same thing?
Maybe, but I've always seen "add" followed by number (as in "Gadd2"). I don't think I've ever seen "add" followed by a letter.
In the case of my Gadd2 example, you play a normal G but leave the A string (the "2" of G) open, so you are in effect adding a 2 (an A) to the G: 300003.
However in the case of CaddG, G is already part of the C chord (hence the open 3rd string), so to me, CaddG doesn't make much sense.
I did a Yahoo search and it so happens that someone asked the question: "How do you play the CaddG chord on guitar? I can't find it."
The answer given was: "Probably because there's no such thing. The C major chord is made up of the C, E, and G notes already. Adding another G is superfluous, from the standpoint of naming the chord."
Anyway, I hope this helps.
PS: Another thing - your original chord tab you asked about was x32013. This is simply another type of C chord, but has an extra "G" in it on the high end (first string, 3rd fret). So I'm thinking that "CaddG" may be a cool way to differentiate that particular C chord from x32010. In short, maybe CaddG = C but add another G on high. Topdown is correct in that x32013 is definitely not C/G.
