Rocksmith doesn't like to read below a Low C on BASS more n more songs being done with this issue being ignored... If it's TOO LOW Transpose BEAD to CEAD - BASS - Lowest i believe the Game likes... and only lose a a small % of notes for some songs whereis: Korn's Fieldy using 5-string Drops 1-step lower again so no way to get true notes to be recognised... The Mudvayne Dig BASS is a good example, at most i can Score about 60-70% cause the RED Open notes aren't counted...
