DEMO - The USB Guitar
The USB guitar is here.
It's called iGuitar.
In addition to providing a direct link to your PC based recording software, it also is a I/O device which can control the software in lieu of a mouse or keyboard.
It wasn't a Gibson Flying V, but it was pretty cool nonetheless.
They said it will retail for about $750 when it comes out later this year and they intend to license the technology to all the guitar manufacturers who want to offer this functionality.
I'll let the guitar players weigh in on whether this is cool or not.
