How can I stop the vibration or sound proof my bass/drums/other instruments in my basement without spending a ton of money?

I have a jam room in my basement in the house I bought, however there is no insulation, the music can be heard throughout the house. I have bass/guitar/drums/other instruments. Any suggestions on how to muffle the sounds without having to spend a ton of money? I am working on a couple of ideas, not sure if they are going to work, so I’d be pleased with any suggestions.
