Can you play bass guitar on PS3's Guitar Hero 3?

If you have a Guitar Hero guitar, you have to play multiplayer. For the first Rock Band, you can't play bass on Solo Tour mode, but it allows you to on every other one. You use the guitar controller normally and, right before playing a song, it will ask you which of the two (guitar or bass) you would like to play. Select bass and it will have you play bass notes.

On Rock Band 2, you do the same thing. This version allows you to play bass on every mode.
