My strum bar sticks

[JokerSRH]

My strum bar appaers to stick when you click up. Is there a quick fix or am I screwed? I noticed this when entering data on a new character. Now I know it's the guitar when I miss a note!!!!

Not sure about a quick fix or not. About the only way I can think of to see why it's sticking would be to open the guitar up and see if it's something obvious.

If it's still under warranty you could return it.
