Hey guys, i have a quick question if its possible to let Rocksmith play back the Songs without the Real Tone Cable plugged in? I currently have only a Acoustic on hand, but want to revise some songs, but if im going to play back the songs, theres a error message popping up that says there is no cable yadda yadda. Obviously all is working as intended, but it stops the song for me, and i wanted to know if i can sort of stop that error message from popping up, so i can play along without any Input? Cheers, Latsch
