I was lucky enough to see Joe 30 minutes ago live here in Chile and I was amazed with this new flamed-finished guitar. He played 3 songs with it: Time Machine, Oriental Melody and Friends (this one at the end of the show).
Of course, itīs the guitar posted above in this topic, but thereīs something you canīt notice there: the finish of the body is the silvered one you see on the chromeboy (or JS10th) guitar. So, itīs not just a normal JS1000 guitar with flames on it! And the finish on the back of the guitar seemed like the 90th (green-to-purple) finish, although it could have been an optic effect on that one.
I hope this helped a bit and it would be great if someone can post some more pictures of this guitar.
