Talismoon has announced a new guitar controller, shaped like the Gibson Flying V, called the "Rock Thunder Guitar."
What's cool about it is its compatibility with all versions of Guitar Hero and Rock Band for Wii. And it's wireless, has a five position switch for choosing guitar effects, and a tactile feedback strum bar.
The best part? It has its very own motion sensor which means that you do NOT have to insert your Wiimote into the guitar when playing Rock Band (sorry Guitar Hero).
