I think you meant to write XX3433 (instead of 3343XX)
The chord sounds good to me.
A barred G would be 355433
So just take your pinky off of the D string to get the G7.
Here's a picture of an F7 chord:
Slide that fingering up (towards the bridge) two frets. (the pinky is off the the string)
It's the rock that gives the stream its music . . . and the stream that gives the rock its roll.
It's a G7, but it's a little strange fingering and it requires quite a grip on that 4 string barre
What I do when I teach it to beginners, is make it a 2 finger chord. How?
3x30xx
Later I'll make it a Jazz type voicing
3x34xx
Hope this helps. I don't use tabs at all, but I teach and transcribe by ear (25 years experience).
