Avoid losing fans after failing a song in Band World Tour mode
If your band fails a song, unplug one of your instruments (it must be a wired instrument). Use a different instrument controller to select the "Return To Main Menu" option. Once you are back at the main menu, select Band World Tour mode to continue your career without having lost any fans.

Guitar solos
Hammer Ons and Pull Offs are a great way to nail solos. If you see a note with a smaller note coming up after it, that indicates you can Hammer On.

For guitar solos (where the background for the notes turns blue and a percentage meter appears) on the Fender Stratocaster guitar only, use the solo buttons (the small ones near the body of the guitar). You do not have to strum; just tap the buttons as the notes pass the bar. This makes solos with lots of notes easier. Note: You may want to use the included guitar strap to keep one hand on the regular fret buttons and the strumming hand on the solo buttons.
