There was an enclosed glass diplay showing the 2 new guitar controllers for Rock Band 3 - the Mustang, which already has pictures on the web since last week, and the Stratocaster Pro controller. As promised, the Stratocaster is basically a real guitar tweaked to work with the game. As you can see in the photos, it has real strings and a plug-in to connect to an amplifier. The difference is the addition of some buttons. What exactly the buttons do was not specified on the display, nor was there a price. Considering that the Mustang, which is only slightly smaller than the real-guitar-sized Strat, will be $150, I expect the Stratocaster Pro to be quite pricey. Nonetheless, it looks like it could be a great item for anyone wanting to make that next step toward using a music game to learn to play real guitar.
