Last time we saw the Gibson Robot Guitar
it was in the hands of Yngwie Malmsteen, who was laying down gorgeous, undulating waves of pure classical-metal fever. The first version of the self-tuning Les Paul was a rather limited edition, but now Gibson is sharing the wealth by introducing two more widely available models. The guitar-maker will issue the original iteration of the axe, but it will now be joined by Gibson's other familiar face, the SG. Both models will apparently be available in a funky, purple-metallic finish (which we suspect only Prince could truly love), and will go on sale for a "limited time" -- though Gibson hasn't said what the cutoff will be. So, if you've got $3,999 for the Les Paul, or $3,599 for the SG, now might
be the time to buy.
