This t-shirt has a completely playable guitar built right in, including a mini-amp which you can strap to your belt. Strum by waving the included magnetic pick over the frets. The volume knob actually goes up to 11 for that little something extra and the tone knob actually works.
All the major chords are included so you can totally jam with other players, maybe bust out a little blues riff. Hit the jump for a video demo.
