All right, for the most part I'm happy, but I've got some issues so let's cram them all into one rant:
1. Has anyone else started playing co-op career using the Les Paul as lead guitar and the old Xplorer as bass?
Three times over the course of eight songs the Xplorer controller simply stopped responding. Thankfully, it only seems to happen while navigating the menus and not in the middle of a song. The quadrant is still lit on up the rings of light on both the controller and the console, but no buttons, including the Xbox Guide button will register.
It was solved each time by unplugging & reinserting the USB cable. I've never had a single issue with the Xplorer in GH2 so I'm thinking it's another GH3 bug. Hopefully, this will be fixed through a software patch.
2. I take back what I said about the Les Paul being dreamy. The tilt that triggers the star power is WAY too sensitive. More than once I've accidentally triggered star power when it was not intended. This is particularly frustrating now that I've gotten into the much harder songs where I need to save it for a particular sequence to survive.
3. No matter how much I try to calibrate the whammy bar in the option menu, it still feels like there is too much of a dead zone resting position. I really have to work it over to get a reaction out of the whammy bar, which usually results in me accidentally triggering the way-too-sensitive tilt sensor.

Anyone else experience these or am I alone?
