i saw this for sale online and i was interested in getting it since it had the 5 colored keys on it. i need that cause i only have the pro guitar which i got from a bundle. i am still learning how to play RB since it is important that i get the easy guitar with the 5 keys. can anyone tell me if the stratocaster in this picture is compatible with Rock Band 3? the seller confirmed it has the 5 keys and that it is for xbox 360 which is the system that i have. if someone knows please let me know. many thanks in advance.
