A solution that can’t tell what string you’re playing is probably not feasible, since RB3 requires you play the expected fret of the expected string.
Right, this is really the key point and probably final nail in the coffin for me.
As Alternity suggests, you’re not going to find a DIY solution easier or cheaper than just getting a RB3 Mustang or Squier pro guitar controller.
Yes I agree. The Mustang is not really what I am interested in, the Squier would be, but I won’t go out of the way to get one.
I was hoping to find a way to redeem the guitar in the game but maybe it’s just not going to happen.
If you don’t care about scoring, just connect the MPA to the game, play the track with no-fail and play along with your real guitar connected to an amp. Or if you want feedback from a game, Rocksmith will be a better option. If you can get it, Bandfuse was pretty cool too. Phase Shift can also play RB3 style pro guitar charts so you can play along with it using an out-of-game guitar as well.
