So, I pick up Guitar Hero II last night after giving it a rest for a couple of weeks. I had been having to hold the guitar upright for increasingly long times to get the star power to activate. But last night, it would not activate at all. I literally have to bang the guitar with my hand to flip the gravity switch and that is even more disruptive than just finding the 'back' button. I searched teh interwebs to see if anyone had fixed the gravity switch in their guitar controllers, and while I found hundreds of entries on the whammy bar, I found nothing on the gravity switch. I am fairly confident around circuit boards, but on the pictures I saw for the whammy fix, I saw nothing that looked like a gravity switch. Can anyone help?
