No flash plug
Not that I spent a lot of time hanging around by the Arena cafeteria, but when I did, I couldnt help but notice this interesting multi-discipline digital guitar from You-Rock.
Featuring USB, MIDI, Audio and game connectivity, its can hook up to pretty much anything. Somewhat simillar to the Yamaha EZAG guitar, but with a touch sensitive fretboard instead of buttons (which the Yamaha uses).
Check it out.
Expected to be $199 Retail
