Blackstar AmPlug 2 Fly Bass headphone amp. It's a tiny little amp to practice with. Plug some headphones in (or use it as a direct out preamp if you want) and get some extra tonal capabilities without having to be tied to a larger, actual amp.
These are $55 new, this one is barely used for a lot less. I got it as part of a trade deal and I actually already have a different amp for this purpose, so someone else should benefit from its existence.
Oh, and since it's TB:
