-Use a rubber band to hold down the whammy bar so it will do the whammy for all long notes. At the end of the song you will get the Whammy Maestro bonus and some extra money. This also helps you get more points.
-There are two songs in Bass Career mode that can give you $200 to $280 in Easy mode and about $300 in Medium mode, "The Joker" (Steve Miller Band) and "Overkill" (Motor Head). To get 100% notes and no star power usage, make sure it is at maximum power and use a rubber band to hold the whammy bar down. This will result some extra money, but if you miss just one note you will only get roughly $120 to $155 in Easy mode.
-A couple more songs you can get $200 or above on is "Band On The Run", "Spiderwebs", "Prisoner Of Society", and "Crazy Train".
-Play "Mountain Song" by Jane's Addiction on guitar under the Easy difficulty setting. This is a very easy song and offers $600 when done with five stars.
