Activison Prohibits You To Use Guitar Hero Guitar On Rock Band
This is some of the fine print on the back of the box:
“Activision authorizes use of this Guitar Hero Game only in combination with Guitar Hero controllers provided by Activision or standard gamepad controllers provided with the game console or other Activision licensed controllers. Any other use is expressly prohibited. No other license, express or implied, is granted.”
“Hey….Hey…I do what I want!”

That’s not what it says. It says the GAME can only be used with official GH controllers. Meaning you can’t use third-party or RockBand controllers on the GAME.
That says absolutely nothing about using the controllers elsewhere.

I like their guitars better then third-party ones anyway.
