If you're going to rock out, you might as well do so with a video game console from the '70s as the core of your guitar. In fact, this is precisely what modder cTrix has done with his gATARI2600. In his configuration, he's able to write and play new music through an Atari 2600 by using an EPROM programmer (a software application he wrote) and daughterboards to feed the new music back through the instrument. The gATARI also features equalizer and flange pedals, a track selector, and whammy bars that allow the player to switch tracks and make changes on the fly. No details have been posted as to how to make your own just yet, but click past the break to watch cTrix jam both thoroughly and effectively at Blip Fest 2011 in Japan.
