Activision has updated the official Guitar Hero: On Tour Web site with new content, including 16 custom skins for the DS plug-in grip.
Among the new designs are multi-colored variations of the Guitar Hero logo, a hard-rocking alien robot and a hellish motif with chains, bones and a fist rising above the flames.
Head over to the Guitar Hero: On Tour site to download a design, print it out and customize your cramp-inducing plastic grip.
