Hi, I'm usually the last person to post for help on a forum, but I've had no luck finding any answers. I have a pretty decent amount of CDLC for 6 string bass and just purchased a fretless 6 string so that I can learn them, and it was my understanding that if I had the 6 string bass plugged in and an extended range bass plugged in, that maybe the game would recognize that and the songs would be playable (any extended range bass songs that I have are X'd out when I'm under the Bass tab and when I try to select them, it switches to guitar.) I just really want a solution to this so that I can get the most out of my new toy and jam out on my new 6 in 2014 like in the Steven Jackson videos.
