Almost 2 years late I know, but like the other guy said, it's a guitar called the kramer striker that was released for gh3 on the ps2. The build quality is actually pretty good, frets and strum bar both feel nice, but it is seriously bottle necked by the fact that it's a wireless only guitar. If it was a 360 guitar then it'd actually be a good guitar, but wireless ps2 guitars were always known for having latency issues. Like the other wireless playstation guitars, it requires a receiver to work.
