It powers on, and blinks when you press the PS button, but I don't have that wireless adapter piece to test this guitar further with.
It's in good shape, and the buttons are tight. Has marks/scratches.
I don't know if anyone would be interested in an untested guitar controller, but who knows. I figured I'd put this up in case someone might be.
Also have an extra guitar neck.imageimageimageimageimage
