It's for the 360. One is wired and the other is wireless. Some people say that the Xplorer kicks the arse of Les Paul due to it being wired so the input is much better and there's no lag (that's what they say). But is it really better? I'm getting a 360 this Xmas and when I do, I'll sell my Guitar Hero 3 and Aerosmith to a mate so I can buy GH2, only if the Xplorer is better than les Paul. Also, are there more faults found in the GH2 guitar than the other? Thanks in advance.
