Song difficulty for bass

[LUFC93]

Does anyone know how to get each difficulty list for the bass, e.g beginner, apprentice. I can get it for the band, vocals, drum and guitar but not bass

There's no way to do so in Quickplay, but you can see the list by selecting Leaderboards from the main menu, then bass.
