Well, if you're desperate, you can try eBay for the add-on.

im hoping for some custom homebrew that uses it. Possibly trumpet hero? you can use the mic to blow into!
Hehe, trumpet hero would probably suck. But homebrew is something I hadn't thought about. The Melody Otario homebrew would benefit hugely from using it. Not to mention people could probably make custom songs for GH (though that'll probably take a while, seeing as it's only 4 frets, you can't just rip already made songs on the internet or on former games). Awesome piece of kit to play with though!
