Good idea? Bad idea? Terrible idea?

Just for practice, not terribly concerned about tone, I just want to be able to hear myself play along to tracks. Is there anything terribly wrong about running my jazz Bass directly into my dad's Roland CM-30 Monitor, or should I be good to go with doing that?

I learned that there are easy ways to waste your life away when all you have is a computer and a world full of people putting new and interesting things on their boners.

Wow, I've been here for a while.
