Who gets to be the guitarist when both axemen select “Guitar”?
The game randomly decides who gets it. Common ettiquette says that you should switch off between bass and guitar so that one person isn’t bored silly the whole time (yes, there are fun bass songs, but they’re fewer than fun guitar songs). Those on the 360 might have a better time negotiating this, thanks to voice chat. Of course, there are those weirdos out there who play just bass. If that’s the case, try not to pick too much Judas Priest, no matter how awesome the solos to Electric Eye and Screaming for Vengence are. Try those songs in bass to see why.
