When I was a kid, my grandfather would buy me a plastic toy violin whenever he thought I needed a haircut. It was his way of saying my curls looked like Beethoven's, which he thought was a bad thing. I kind of liked Beethoven's long hair, and I definitely liked pretending with those funky plastic violins. Playing with a toy, however didn't turn me into a musician. It is unlikely that Power Gig's new rocker (which comes with a "working, real" guitar will either.
The folks at Seven45 studios must have thought they had the greatest idea: Let gamers get a taste of really rocking by using a controller that doubles as a guitar and let that axe with strings work as a controller for Rock Band as well. And it was a pretty cool idea right up until Rock Band 3 came out (the same year) with an infinitely better, deeper, option.
Let the buyer beware: The Gig's guitar doesn't work with the pro-mode of Rock Band, and it isn't intended to teach you how to play the guitar. What it is, mostly, is an expensive toy; sadly, more gimmick than gadget or musical instrument. Yes, it will let you strum some chords, but it will have trouble staying in tune, too. Instead of learning to play, the power chord option seems more like an add-on decided to feature compete with last year's version of Guitar Hero (with which it shares a cheesy plot).
Whether you want to really learn to rock, or just have the arcade experience, I'd stick with Rock Band 3.
