Well it seems like there are a lot of people having a range of problems. I feel I however have the worst controller I've read about so far.

I barely get into a game or even past the main menu screen and my controller goes crazy. There are two main things that go wrong for me.

The strum glitches and the menu selection repeatedly loops through the menu. Even after recalibrating, by re-connecting making sure everything is in its normal position, strum, analogue stick etc...

If I use two or more things at once and sometimes just one, the whole guitar will completely freeze and I have to unplug.

If by chance I do get to start a game, I only manage to play about 5 notes then the guitar freezes again. It's totally unplayable. Taking it back today.

I would love to open her up and try and work out what the hell is going wrong but I don't want to void it's warranty
