The Zoom B1on is dirt cheap and you can plug your bass directly into it as well as your computer or phone/tablet/mp3 player. No need to even turn the amp on, and you can practice anywhere.
As i've also found, you can go from the output to a small speaker and still jam along to your other tracks if you don't want to wear headphones.
This is my travel practice rig.
