Star Power, Gumline Problems: Solutions Revealed.

I just got a xbox 360 les paul (different to the one in a previous post of mine) and im having a few problems with it. First, as soon as i get star power, it uses it automatically and doesnt let. They fixed the problem later with giant buttons on the bridge, but the xplorer is uniquely fuckled for sp. The back button is so tiny it's not even worth trying. Been playing guitar hero and clone hero for years, i'm on v23. 2. 2, and when the star power bar gets at least half full, star power activates automatically.

In guitar hero warriors of rock (just an example, this happens in every other gh game as well), star power will automatically activate. This occurs with my guitar hero 5 xbox.
