These are the electronic devices DARK STAR has been using to create most of the basic tracks. Of course there should also be a guitar, but the one DARK STAR is using is not a very special one and there's no picture of it anyway. Same goes for effects (although the prehistoric fuzz pedal actually looks pretty funny...).
