Hi I have been enjoying Rocksmith 2014 and Custom DLCs for 2 weeks so far. However, I have experienced rather weird issue when downtuning to C Standard (e.g. for Alestorm songs, CDLC). Tuning goes well, no problem there. However, the yellow string (still learning, forgive me) is only detected if no fret is held; anything that requires a fret (1, 2, 3 - 21) on a yellow string, it is always a miss. Without a fret, just strumming the yellow string is just fine. All other strings work perfectly fine. On E standard it is also good. Thanks for any help!
