This is the four year old's funky little Tiger Electronics Power Tour guitar and amp which he got for Christmas.
It has a Gibson headstock and it looks like a miniature SG. But there are no strings, only touch pads. There are knobs that control various things like tone (Punk, Metal, Rock and, amazingly Indie) and Jam, Band, Learn and Speaker. "Learn" is interesting as the young would-be rocker has to follow the lights on the "fretboard" as they flash in time to "Smoke on the Water" or the song's count-off will start again, followed by a hearty chorus of boo's rising out of the amp. The whole thing is touch-sensitive, and there's some wicked divebomb sounds accessible, too. High impact plastic, as is the tee-tiny amp with color organ speakers (four three-inch woofers, imagine the bass response). Both, of course, go to eleven.
The functionality of this kit is not terribly versatile, but the whole outfit was about $45, thanks to Smart Wife's intrepid shopping talents (the real retail is closer to one hundred bucks). I'd say we've gotten that much out of it already. The four year old still probably favors the acoustic guitar, although he gives out some great 'guitar face' when he plays this one.
