For product one can only say that it works at least as far as the sounds are heard.
For the uninitiated, the emerging in-game latency, however, not to remember, I say jetz times quite cheeky (Professional musicians see the certainly different, but if we were to, we would not have to play this game: P).
Of course it can not be compared with direct 6.3 jack or XLR, but that we all know.
By my opinion, weak integrated interface and the USB connection convinced expect the cable is not necessarily by sound quality or speed, but you should not.
The price for such a cable, of course, very high and probably inappropriate. But what does it not everything to play this game.
If you want to set this cable, it should think twice, as even the new Rocksmith still has many teething problems and has been improved by the controller, but still not "good".
However, if everything is installed and adjusted again, it makes a lot of fun, the question is whether that makes all the problems and annoying quirks betting.
