Trade something (cell phone, game system, bicycle, etc) or pick up odd jobs for either a business or neighbors. If in a neighborhood, offer your services for $20/hr: help move furniture, lawn work, painting - sometimes people just need a hand with some stuff and don't have anyone to call to help them.
Next bump it up a notch - go to local businesses asking if they need any part time help - even just a couple hours per week. Some places might again find tasks for you to do once a week. Find a few businesses to do chores for, and you'll soon be earning $30/week.
It shouldn't take too long to scrape together $100 using the above three methods. Just note - the thing you don't want to do is steal stuff. Just like it will take hard work and savings to get the money together to buy the bass, people have worked hard for their stuff too.
